TANTYDENIM / Development Guide

Custom denim development: from sample to production

TANTYDENIM is a Guangzhou-based custom denim development and production coordination partner for brands sourcing custom jeans in China. Our job is not simply to find a factory that says yes. We help turn your brief into a workable development route, keep fit, wash, construction and approvals aligned, and make the next decision clear before bulk production starts.

You do not need a perfect tech pack to start. Send the reference, sketch, sample garment or measurement sheet you already have. We will tell you what is already clear, what still needs confirmation, what affects MOQ or price, and what needs to be proven in a physical sample before you commit to bulk.

Low-MOQ custom jeans development in China

TANTYDENIM coordinates private-label jeans development and production with selected manufacturing partners. Start from your own design or a previously produced base style; fit, fabric, wash, construction and branding are reviewed against the actual order.

Standard order: 50 pcs: Per style and colour, with mixed sizes available. A 30–49-piece trial needs a separate feasibility review.
Customisation: Fit and measurements, denim selection, wash direction, construction details, selected labels, hardware and packaging.
Sample target: 5–7 days after key development details and the material route are confirmed. Special materials, processes or revisions can extend the schedule.
One point of contact: Summer Tan coordinates the brief, production-partner communication and the approval points you need to review.

Planning 50 pairs or 100 pairs?

Decision	50 pcs per style and colour	100 pcs of the same specification
Unit cost	Higher unit cost because setup work is spread over fewer garments.	Setup costs are spread over more garments. Request a quotation for the same fabric, wash, construction and trims.
Sizes and colours	Mixed sizes can be reviewed within the style/colour quantity; confirm the size ratio.	Mixed sizes can be reviewed. A second colour or wash needs its own feasibility and quantity check.
Materials and branding	Available denim and standard components can make a small run easier. Custom fabric or hardware may carry separate minimums or tooling costs.	Fabric, trim and wash minimums still need confirmation; 100 garments do not automatically meet every component minimum.
Before production	Confirm the selected materials, physical sample, specification, price, schedule and quality checkpoints for the actual order.

For 30–49 pieces, send the same brief for trial-order review. We confirm whether the fabric, wash, trims, construction and size breakdown support that quantity before you commit.

What Happens After You Send Your Project

For a practical example, review our sequin and chain sourcing case with measurement photographs. For other project stages, compare low-MOQ, startup, private-label and women’s sampling routes.

You should know the next step before you pay for a sample.

We do not treat an enquiry as a cue to rush into a quotation. First we separate what is already decided from what is still open, then check whether the quantity, materials, wash and construction can be handled on a realistic production route.

01 / Review

We read the tech pack, images, measurements or reference garment and mark the decisions that are already clear.

02 / Gaps

We identify missing information that could change fit, wash, construction, MOQ, price or timing before sampling begins.

03 / Feasibility

We check the style against suitable production partners, material availability and the actual quantity instead of promising from a photo alone.

04 / Sample Route

We confirm what the first sample is meant to prove, what remains temporary and which decisions need your approval.

05 / Approval

Fit, measurements, wash direction, trims and the current specification version are closed before the sample becomes a bulk reference.

06 / Bulk Coordination

Only after the approval points are clear do we coordinate the production route, checkpoints and shipment preparation around the approved standard.

Start With a Brief

The decisions that make or break the first sample

Most first-sample problems do not start at the sewing machine. They start when a reference photo is treated as a complete specification. This table shows what we ask for, and what still has to be decided on the actual garment.

Development decision	What the brand can send	What should be confirmed
Product direction	Reference image, sketch, tech pack or existing sample	Category, silhouette and intended market direction
Fit	Measurements, fit comments or reference garment	Base-size fit, wearing position and key POMs
Fabric	Composition, weight, stretch, handfeel or fabric reference	Selected fabric and how it supports the target fit and wash
Wash	Shade reference, effect images and written comments	Approved wash direction and physical sample standard
Construction	Drawings, callouts or reference details	Seams, stitching, pockets, waistband, fly and other style-critical details
Trims and branding	Artwork, labels, hardware and packaging direction	Material, finish, dimensions, placement and approved versions
Size range	Target sizes and any existing grade direction	Base size, grading logic and size-set review needs
Quantity	Expected quantity per style, wash and colour	Whether the project fits the starting MOQ and material/process constraints
Approval status	Latest comments and revision files	Which decisions are approved, pending or still under review before bulk

Send what you have. We will work out what is missing.

A reference image is often enough for the first conversation. It tells us whether you are aiming for a low-rise baggy shape, a clean straight leg or something more fitted. It does not tell us the finished waist, rise, fabric stretch, pocket size or how the wash should look in normal light.

If you already have a garment that fits well, measurements or a tech pack, include them. Also tell us the quantity, size range and the details you will not compromise on. That is more useful than a polished brief with no priorities.

MOQ Clarity

Custom denim MOQ: standard 50 pcs, trial orders reviewed from 30 pcs

Standard MOQ is 50 pcs per style and colour. Trial orders from 30 pcs per style and colour may be coordinated after reviewing fabric, wash, trims, construction and size breakdown. Mixed sizes are available. Standard and trial-order pricing depend on the actual specifications. For the same style, colour and specifications, a 30-piece order has a higher unit price than a 100-piece order. Request a quotation for your actual quantity. Colour splits and final workable quantity are reviewed against fabric, wash, trims, construction and size ratio before confirmation.

The number is only workable when the chosen fabric, wash and trims can also be sourced at that scale. For example, a stock denim and standard hardware can be easier to arrange for a small starting run than a specially woven fabric or a custom-plated button. We check those constraints before confirming the order.

Can a project below the usual MOQ be reviewed?

Standard MOQ is 50 pcs per style and colour. Trial orders from 30 pcs per style and colour may be coordinated after reviewing fabric, wash, trims, construction and size breakdown. Mixed sizes are available. Standard and trial-order pricing depend on the actual specifications. For a quantity below 30 pieces or another special requirement, ask us on WhatsApp or send your project brief through the form. We review the style, fabric, wash, trims and size split before confirming whether an exception is workable.

If a smaller run is workable, we explain the conditions before you decide whether to proceed. Unit cost can be higher because cutting, sewing, washing, finishing and QC still require setup even when the quantity is very small.

A below-standard run is a project-specific exception, not a blanket MOQ promise. We confirm it only after the real product requirements have been reviewed.

Fabric Stock-supported denim and specially sourced fabric can require different development arrangements.
Wash Clean rinses, vintage fading, abrasion, laser artwork and detailed effects require different approval points.
Trims Custom buttons, rivets, labels, patches, hangtags and packaging may have separate supplier requirements.
Size ratio Mixed sizes are accepted, but the intended size breakdown should be confirmed before production.

Small-Run Reality

A small trial order only works when the setup is workable.

In recent small-run enquiries, the useful question has not been simply whether a factory will accept a low number. We first check how many styles are involved, whether the fabric is available, how complicated the wash is, whether custom trims create separate minimums, how the sizes are split and what still has to be proven in sampling.

That review can sometimes make a below-standard trial quantity possible. It can also show that the requested number is not realistic for the chosen construction or materials. Either answer is useful when it comes before the brand spends money on development.

The goal is not to collect a quick “yes.” It is to make the conditions, open decisions and next step clear enough that both sides know what has to happen before production can start.

Private-Label Sampling Guide

From technical direction to the first sample

Pattern preparation and cutting , production-partner process evidence.

Sewing and garment construction , production-partner process evidence.

This is where a drawing becomes a garment. The pattern maker needs actual measurements and balance; the sewing team needs seam, pocket and waistband details; the wash team needs to know which shade and effects are intentional. TANTYDENIM keeps those decisions together while coordinating with the production partners used for the style.

The short videos in our pattern, cutting and sewing evidence show the work between an approved brief and a sample you can put on and review.

Why we sometimes compare more than one sample route

For some developments, we may sample with two or three production partners in parallel rather than relying on the first workable route. We compare how each one handles the construction, wash, and the details shown in the design reference.

This is useful when the execution itself is still uncertain. Two sample rooms can read the same brief differently, especially around wash effects or construction details. Using the same brief for each sample makes those differences easier to judge.

Before choosing the stronger route, compare the same points on every sample:

Fit and pattern interpretation: did the sample keep the intended rise, hip balance, leg shape and key measurements?
Wash execution: did shade, fading, whiskers and surface character stay close to the reference rather than simply look “washed”?
Construction: check seam quality, pocket placement, waistband shape, topstitching and the details that affect the finished silhouette.
Revision response: can the sample room turn comments into a cleaner second sample without creating new problems elsewhere?
Production fit: are fabric MOQ, trims, wash process and realistic order quantity compatible with the project?

The lowest first quote is not automatically the strongest route. The useful comparison is which partner can repeat the brief with the least ambiguity before bulk production.

Once the stronger route is clear, the next revision moves forward from one controlled set of comments and specifications. Parallel sampling is a comparison step, not a reason to keep several versions of the product in circulation.

How the first sample actually starts

We first separate decisions from preferences. The intended fit and the non-negotiable construction details need to be written down. Fabric and wash can then be narrowed to options that support that fit and are realistic for the quantity. Anything still open stays marked as open, so a temporary button or preliminary wash is not mistaken for an approval.

How long does a private-label jeans sample take?

After we review the brief and confirm the material and wash route, we give you a working sample schedule and explain what that estimate assumes. A straightforward five-pocket jean using available materials can move much faster than a style with custom hardware, a shaped waistband or several wash trials.

If sourcing, wash development or a revision changes the schedule, we update the timing instead of leaving the original estimate in place. The important point is that you know which step is waiting on us, the production partner, a material supplier or your approval.

What information should be included in the sampling brief?

A tech pack, sketch, reference image or existing garment
The intended fit, rise and leg shape
Target measurements and size range
Preferred denim composition, weight and stretch direction
Wash reference, colour direction and intended hand feel
Pocket, waistband, seam and closure details
Buttons, rivets, labels, patches and packaging requirements
Quantity per style, wash and colour
Delivery country and intended timing

Tell us where we have room to adjust

One sentence can save a full revision: tell us which details are fixed and which are directional. If the leg shape is fixed but the exact shade can move, say so. If the branded button is essential but the pocket stitch is not, mark that too.

This lets the development team solve real constraints without quietly changing the parts that define the product.

Development Decisions

Review the garment as one connected product

Fabric and fit

Confirm denim composition, weight, stretch direction, hand feel, intended rise, waist shape, hip fit, inseam and leg opening.

Wash and finish

Confirm the base shade, fading placement, contrast, abrasion, visible effects and intended finished appearance.

Construction and identity

Confirm pockets, seams, closures, hardware, labels, patches, branding details and packaging requirements.

Before Bulk Production

Before bulk, make sure everyone is approving the same garment

The physical sample and the latest specification need to match. Check the finished measurements, fit, fabric, wash, construction, pocket placement, hardware, labels and packaging on the version being approved, not on an earlier photo or an old spreadsheet.

Keep that sample as the bulk reference and record its version and date. If an important change was accepted in email or chat, move it into the controlled tech pack before cutting begins. Otherwise two different versions of “final” will circulate.

“The sample looks good” is not a complete bulk approval. Before cutting, we want the approved sample, current measurements, wash reference, trims and specification version to point to the same product.

What should be agreed before a denim sample becomes the bulk standard?

Before approving a denim sample for bulk, agree the finished measurement tolerances, fit and size-set status, physical wash reference, approved trims, quality checkpoints and specification version. A sample approval should say exactly which of these decisions it covers.

Measurement tolerances: record the target and allowed plus/minus variation for each point of measurement, the measuring method and whether the garment is measured before or after washing. Agree tolerances for the selected fabric and wash; one blanket allowance may be unsuitable for the waist, rise, inseam and leg opening.
Fit and sizes: close the base-size fit comments and record which sizes still need review. Approving one sample size does not confirm the whole size range.
Wash standard: identify the physical reference for shade, fading placement and hand feel. Record any acceptable variation and any additional shrinkage or wash tests required.
Trims and construction: confirm hardware finish, label artwork and placement, seam details and attachment. Mark any temporary sample trim as pending.
Quality checkpoints: agree who checks materials before cutting, construction during sewing, and measurements, appearance and attachments after washing and before packing. Record the defect criteria, sampling or inspection scope, and how failed checks are resolved before shipment release.
Revision control: put the approved sample reference, date and latest comments into one controlled specification. Any later material or process change needs review against that standard.

Use the fit and size-set approval guide for measurement decisions, the wash guide for the physical finish reference, and the production and quality guide for review checkpoints.

When laboratory or destination-market testing is required, write the test method and acceptance level into the brief. “Must pass testing” is not a usable production instruction.

What We Can Confirm — And What Needs Development

Useful certainty is better than a promise we cannot control.

What we can make clear

What information is missing before sampling or quotation
Whether the proposed quantity is workable for the actual style
Which sample and specification version is being reviewed
Which fit, wash, trim and construction points still need approval
Which production checkpoints will be used before shipment
What the current timing estimate depends on

What we do not pretend to know too early

An exact final price from one reference photo without material and construction details
That every style below the normal MOQ can be produced
Zero shade variation in washed denim
A fixed delivery date before materials, sample approvals and open decisions are checked
That one approved base-size sample automatically approves the full size range

Buyer FAQ

Questions before you request a quote

What will we clarify before you decide to proceed?

We check feasibility with suitable production partners before confirming the route, quantity, price and conditions. We prepare the available project information you need for that decision and explain the next steps, estimated timings and anything still awaiting confirmation.

The schedule should make clear which dates are estimates and which depend on materials, your approvals or another open decision. You can review those points before deciding whether to proceed.

Can garments in the same batch have different wash shades?

Yes. Shade differences can occur within the same production batch. Before bulk, we agree a physical wash reference and an acceptable shade range with you and the production partner. Record how shade will be checked and how garments outside that range will be handled. An approved sample does not mean every garment will have exactly the same colour.

How should I compare denim weight, composition and stretch before sampling?

Start with the fit and wash you want, then compare fabric options against those requirements. A weight number or fibre composition describes an option; it does not approve the finished garment.

Weight and drape: send a fabric or garment reference and the available weight specification. Record whether that weight refers to fabric before or after finishing. Compare the washed sample with the structure and drape you want.
Composition: record the full fibre blend for each option. If your target market needs a particular material claim or test, include the requirement and the evidence needed before approval.
Stretch and fit: state whether the style needs rigid denim or stretch, and in which direction. Review movement, recovery and the key measurements on the finished sample rather than choosing by a fibre percentage alone.
Wash and availability: use the intended wash in the comparison and check the available fabric quantity for the proposed order. Keep any alternative fabric clearly marked until it has been reviewed.

Choose the fabric after reviewing the physical swatch and, where needed, the garment sample or agreed tests. Record the selected fabric reference in the current tech pack. If the fabric changes, review the affected fit and wash decisions again.

Use the fit and size-set approval guide for measurement checks and the wash guide for the finished reference.

Who decides whether a denim fabric is right for the project?

Your requirements guide the choice. Composition, weight and stretch direction can be written into the brief. Hand feel and the finished appearance need your review of physical swatches or samples; people can judge the same fabric differently.

We help source options and arrange samples or tests needed for the decision. The fabric choice stays pending until you have confirmed it against your requirements.

Can TANTYDENIM develop jeans from a reference image?

Yes. A reference image can provide a starting point for discussing the silhouette, construction, wash and visible details. It should be supported by measurements and written product requirements during development.

Can fabric, fit and wash be customised?

Yes. TANTYDENIM supports custom fabric, fit and wash development. The practical route is reviewed against the product brief, quantity, required appearance and project timing.

Can a brand add private-label details?

Private-label development can include selected buttons, rivets, labels, care labels, patches, hangtags and packaging. The available options are reviewed after the product requirements are clear.

When should I send an original reference garment?

If fit, construction or finishing needs to be copied closely, a physical reference garment is usually more useful than photos alone. It lets us check measurements, seam construction, pocket placement, internal finishing, fabric feel and the details that are difficult to judge from a screen.

You can still start the conversation with photos or a tech pack. We will tell you if the physical garment is likely to improve the accuracy of the sample before you send it.

Does TANTYDENIM accept mixed sizes?

Yes. Standard MOQ is 50 pcs per style and colour. Trial orders from 30 pcs per style and colour may be coordinated after reviewing fabric, wash, trims, construction and size breakdown. Mixed sizes are available. Standard and trial-order pricing depend on the actual specifications. For the same style, colour and specifications, a 30-piece order has a higher unit price than a 100-piece order. Request a quotation for your actual quantity. Colour splits and the final workable quantity are reviewed against the actual project requirements. Send your preferred size breakdown with the brief.

What should I send a custom jeans manufacturer before sampling?

Send the product category, reference image or tech pack, target fit, fabric and wash direction, trims, size range, quantity, delivery country and intended project timing.
