Sampling Process Guide

Why Sampling Is the Most Critical Yet Underestimated Step in Brand Development

Many startup founders see sampling as just a "make one to take a look" step—get it roughly right and rush to bulk. That's a dangerous misunderstanding.

A sample is not just fit validation. It's simultaneously:

Your first physical experience of the fabric's hand-feel (drape, recovery, and skin comfort can't be judged on screen)
A feasibility and cost test for production techniques
The first physical carrier of your brand's perceived quality—what you use for photography, send to influencers, list for pre-sale

A well-run sampling process reduces rework during bulk, shortens time-to-market, and prevents batch-wide quality incidents. A compromised sample process, on the other hand, often replicates a single flaw across 300 bulk units.

📝 Stage 1: Starting Sampling—What You Need to Provide

The speed and accuracy of sampling heavily depend on input clarity. We support clients at different readiness levels:

Best Method: Complete Tech Pack

If you already have a professional Tech Pack, pattern development is direct and efficient:

Technical sketches (front / back / side, CAD or hand-drawn)

Size chart (with measurement method annotations)
Bill of Materials (fabric and trim specs)
Construction details (seam types, stitch indications, special finishes)
Reference sample (if available)

With a complete Tech Pack, our pattern maker can output the pattern within 2 working days and move straight into sample sewing.

Supported Method: Visual Reference + Written Description

If you only have reference images and descriptions, we can still start. Our design team will translate your concept into an executable pattern first, adding about 2–3 working days of conversion time—equally reliable.

Either way, we confirm every detail with you before starting, avoiding "interpretation drift" that leads to wasted sampling rounds.

🧵 Stage 2: Sample Types—More Than One Kind of "Sample"

Different brand stages require samples for different purposes. Knowing what you need avoids unnecessary fees and delays.

Sample Type	Purpose	Best for	Production Standard	Notes
Proto Sample	Validate fit and overall effect	All new developments	Similar fabric acceptable; techniques close to bulk	May have slight hand-feel difference from final bulk fabric
Revised Sample	Verify modifications from proto feedback	Proto not approved, second confirmation needed	Same standard as proto, only specified points modified	Usually 2-3 days faster than proto
PP sample (Pre-production sample)	Final sign-off before bulk cutting	Proto confirmed, minor tweaks only — skip to bulk	Bulk line, bulk fabric, real line workers	Most production-representative; Minghang’s recommended acceleration mechanism to skip unnecessary second sample
Salesman sample	For buyers, trade shows, showrooms	Brand attending order fairs or dealer recruitment	Bulk standard	Usually pulled from bulk or made separately after PP approval
Photo sample	For e-commerce detail pages, brand lookbooks and marketing	After PP confirmation	Bulk standard, extra attention to visual details	Can be prioritized within bulk production to sync photo shoot with launch.

If you're unsure which sample type you need, your sales specialists will guide you during consultation—avoiding excessive sampling or irrelevant revision rounds.

❓ Stage 3: Sampling Timeline—When Can You Hold Your First Sample?

Sample Type	Standard Styles	Heavy-work Complex Styles	Notes
Proto sample	7-10 working days	12-15 working days	Complex styles include cumulative time for screen printing, rhinestones, washes etc.
Revision sample (2^nd)	5-8 working days	8-12 working days	Faster than proto by 2-3 days; pattern base exists, materials already on-site
Pp sample	5-7 working days	8-10 working days	Made on bulk line; fastest and most representative confirmation version

Parallel fabric & trim procurement mechanism—we don't wait for the pattern to be finished before ordering fabric.

Once you confirm sampling and pay the sampling fee, fabric and trim procurement begins immediately. Typically, the fabric arrives in the workshop on the same day or even before the pattern is completed. This means your sampling has virtually no "waiting for fabric" gap—a core strategy behind Minghang's accelerated sampling timeline.

Production-Level Quality Benchmark

Every sample is built to reflect bulk production craftsmanship, ensuring scalable and consistent manufacturing results.

💰 Stage 4: Sampling Fee Policy—Transparent & Deductible

Sampling involves pattern maker hours, sample sewer time, and fabric/trim procurement. Our policy:

First proto sample fee: Charged based on style complexity, clearly stated at quote stage.
Bulk deduction: When your bulk order meets the agreed MOQ, the sampling fee is refunded against the bulk invoice.
Revision sample fees:
- If revisions are due to our process deviation, no charge.
- If revisions are due to design changes or client-requested modifications, charged per actual labor and material cost.
PP Sample fee: Usually waived, included as part of bulk service (provided proto has been confirmed, minor tweaks only).

No Hidden Charges

All sampling-related costs are documented in writing within the contract and quotation—no "later add-ons."

🔍 Stage 5: Sample Review & Feedback—How to Communicate Modifications Efficiently?

80% of delays we see stem from ambiguous feedback. Here are best practices for efficient communication:

Feedback Method	Effectiveness	Recommendation
Mark directly on the sample garment	Best	Use stickers or pins to mark modifications location and direction
Provide before/after comparison drawing	High	Sketch or annotate desired effect vs. Current state
Video call with fit model	High	For fit-critical styles, real-time communication on a live body
Text description like “a bit tight here”	Low	Lack reference; often leads to an extra revision round

Recommended Workflow:

Upon receiving the sample, arrange a fit session on a real person. Take front, side, and back photos, annotate feedback directly on the photos, and send to us. We will confirm the modification plan and estimated time within 24 hours of receiving your feedback.

Why Minghang's Sampling Process Is Different

Common Pain Point	Minghang's Solution
Waiting for fabric before sampling can start	Parallel fabric procurement triggered immediately upon sample fee payment—zero wait
Beautiful sample, disappointing bulk	PP Sample made on actual bulk line, reflecting true production capability
"No second sample, no bulk" forced upselling	PP Sample mechanism replaces unnecessary second samples, saving time and money
Vague feedback, back-and-forth revisions	Guided feedback process, video fit sessions, and real-time communication supported
Sampling fees unpredictably added later	Written upfront quotation, bulk deduction policy in black and white

Frequently Asked Questions

The sample looks great. Will bulk be exactly the same?

Our bulk and samples follow the same construction standards. However, there are inherent physical tolerances between sample and bulk that we transparently communicate:
• Fabric lot variation: Same-spec fabric from different dye lots may have slight weight and hand-feel fluctuations—normal in textile manufacturing. We control color variance at the Lab Dip stage and spec deviation at incoming fabric inspection.
• Production scale effect: A sample is sewn by a single sample sewer; bulk involves multiple workers on a line. The PP Sample (Pre-Production Sample) is specifically made on the bulk production line to bridge this gap, representing more authentic mass-production quality.
• How we control variation: By locking in a signed confirmation sample + fabric swatch + PP Sample as the triple standard, against which bulk is produced and inspected.

Why is the first proto sample fee higher than I expected?

The first proto is a 0-to-1 process for a new style: pattern development, small-quantity material procurement or allocation, and dedicated sample sewer time. Heavy-work styles with multiple special processes amplify this. This fee is refunded against your bulk order once the MOQ is met—meaning we ultimately absorb it.

Can I skip sampling and go straight to bulk?

We strongly advise against this. The risk of skipping sampling is that fit, construction, and material issues only surface after bulk is finished—at which point the cost and time loss far exceed the sampling investment. For repeat orders of established styles, direct bulk is fine. New developments must be sampled.

I'm developing 5 styles. Can I sample them together?

We can propose alternative fabrics, but will clearly state the trade-offs in hand-feel, colorfastness, and stretch recovery so your brand perception isn’t compromised.

I need an extra photo sample. How does that work?

After PP confirmation, we can prioritize one or a few pieces from the bulk line, with extra attention to visual details for photography. We'll reserve this node in the production schedule so it doesn't add to your overall delivery timeline.
