From Concept to Confirmed Sample -- Ready for Bulk Production
YECHENG APPAREL provides structured sampling services for custom hoodies, T-shirts and tracksuits. Whether you have a completed Tech Pack or only a reference image, our team can develop a production-ready sample that reflects your design intent, fabric requirements and brand standards.
Built for Brands in the New Product Development Stage
Our sampling service is designed for teams who are actively developing new apparel products and need a reliable manufacturing partner to help bring the product concept to a confirmed, production-ready standard.
Fashion & Streetwear Brands
Independent brands and streetwear labels developing seasonal or capsule collections who need custom hoodies, T-shirts or tracksuits developed to their design specifications.
- New seasonal product launches
- Capsule collection development
- Brand identity through custom fit and fabric
Private Label & Wholesale Buyers
Buyers building private-label product lines or wholesale programs who require specific constructions, branding elements and consistent quality benchmarks before committing to bulk orders.
- Private label program setup
- Wholesale product standardization
- Pre-bulk quality confirmation
Startups & Growing Brands
Early-stage and growing brands testing new product concepts with smaller quantities before scaling. Validate fit, fabric and finish with a confirmed sample before committing to production volumes.
- Small-run concept validation
- Pre-production risk reduction
- Scalable path to bulk manufacturing
Not sure which starting point fits your project? Whether you have a completed Tech Pack, a reference garment, a sketch, or only a product concept, our team can help you work through the requirements and determine the best approach.
Tech Pack, Reference Images or Sample Garment -- We Work With What You Have
You do not need a complete Tech Pack to begin sampling. We accept a range of starting points and help organize the product requirements into a workable specification before development starts.
Full Tech Pack
Technical drawings, measurement chart, fabric specifications, construction notes, decoration artwork and label/packaging requirements.
Reference Materials
Reference garment, product photos, design sketches, brand mood board or initial product concept with fabric and fit direction.
Key Information We Review at Project Start
Product & Design
- Garment type and intended silhouette
- Fit reference (oversized, regular, slim)
- Construction details and stitching notes
- Decoration placement and artwork files
Fabric & Materials
- Fiber composition and blend preference
- GSM range and hand-feel direction
- Color standards (Pantone or reference)
- Trim, hardware and accessory requirements
Branding & Packaging
- Label type and label placement
- Hang tag and barcode requirements
- Packaging specification
- Target market sizing standard
Every Element Confirmed Before Cutting Begins
Pattern making, fabric selection and production process are aligned with product specifications and approved before the first sample is cut. This reduces revision rounds and aligns the sample with production expectations from the start.
Pattern Development
Measurement & Grading Review
Confirm base size, grading increments and target market sizing standard (US, EU, UK or custom).
Block & Fit Pattern Development
Develop the working pattern based on the design reference, construction notes and target silhouette.
Pattern Confirmation
Pattern is reviewed against the approved specifications before cutting the first sample.
Decoration & Process Confirmation
Fabric Selection & Confirmation
Fabric is selected or developed to match composition, weight, construction and finish requirements. The fabric is confirmed before sampling begins to ensure the sample reflects the intended product quality.
Fabric swatches or lab-dip samples are provided for colour-critical projects before sample cutting begins. The approved fabric forms part of the production specification.
First Sample · Revision Rounds · Final Confirmation
A structured, stage-by-stage process that moves each sample round forward with documented feedback, reducing overall revision cycles and time to production approval.

Production
First Sample (SMS)
The first sample is produced based on confirmed pattern, fabric and decoration specifications. It establishes the baseline for fit, construction quality, colour accuracy and process execution.
- Pattern and grading applied
- Approved fabric and trims used
- Decoration executed as specified
- Measured against the size chart
- Detailed photo set provided for remote review
Revision Rounds
Client feedback is collected in a structured format covering fit, measurements, construction, colour and decoration. Changes are documented and the revised sample is produced against the updated specification.
- Structured feedback form provided
- All changes logged against specification
- Revision scope confirmed before re-cutting
- Repeat rounds handled systematically
- Physical or digital review supported
Pre-Production Confirmation (PPS)
The pre-production sample confirms all approved details at bulk material conditions. Once signed off, it becomes the production standard reference used throughout the bulk manufacturing process.
- Bulk fabric and trims confirmed
- Final measurement check completed
- Labels and packaging reviewed
- Signed-off sample archived as reference
- Production schedule confirmed on approval
Physical samples can be shipped for in-hand review at any stage of the process. Sample shipment costs are confirmed at the time of the project brief.
What We Check on Every Sample Before It Ships
Each sample is reviewed against the confirmed specification across measurements, construction, decoration and branding before dispatch. Issues found during review are documented and addressed before the sample leaves our facility.
Sampling Timeline, Costs and the Path to Bulk Production
Sample lead times and costs vary based on garment complexity, decoration requirements, fabric sourcing and the number of revision rounds. Indicative ranges are provided here; confirmed timelines are provided after project brief review.
| Stage | Typical Lead Time | Cost Basis | Notes |
|---|---|---|---|
| First Sample (SMS) | 7-14 business days | Sample fee per style | Deducted from bulk order in most cases. Confirmed per project. |
| Revision Sample | 3-7 business days | Varies by revision scope | Minor fit changes vs. significant construction revisions are costed separately. |
| Pre-Production Sample (PPS) | 5-10 business days | Included or per agreement | Produced at bulk fabric conditions. Sign-off triggers production scheduling. |
| Lab Dip / Fabric Swatch | 5-10 business days | Per colour per fabric | Required for colour-critical projects. Approval required before SMS. |
| Strike-Off (Print) | 3-5 business days | Per artwork | Print strike-off for screen or DTF confirmation before sample cutting. |
Sample Fee Policy
Sample fees cover pattern making, material sourcing, construction, decoration and quality review. Fees are typically deducted from the bulk order invoice upon confirmed production placement.
Factors That Affect Lead Time
Fabric sourcing complexity, number of decoration techniques, revision scope, public holidays and shipping time for physical samples all affect the total development calendar.
From Sample to Bulk Production
Once the PPS is approved and the production order is placed, the confirmed sample becomes the production reference. Bulk lead time is assessed based on quantity, fabrication and current scheduling.
