Clothing Sampling Process Explained: From Sketch to Final Sample in 3 Rounds

August 1, 202610 min readBy Essty Garment

Sampling is the bridge between your design and mass production. Skip it, and you'll receive 1,000 garments that don't match your vision. Do it wrong, and you'll waste weeks and hundreds of dollars on samples that still aren't right.

As a factory, we produce 50-80 samples per month. Here's our exact process — the same one we use whether you're ordering 100 pieces or 10,000.

The 3 Sample Rounds: What Each One Does

Professional clothing manufacturing uses three sequential sample rounds. Each has a specific purpose:

RoundNamePurposeTimelineCost
1Proto SampleVerify design, fabric, construction5-7 days$30-80/style
2Fit SampleVerify sizing, drape, adjustments3-5 days$15-40/style
3Pre-Production (PP) SampleFinal approval before bulk3-5 days$15-40/style

Round 1: Proto Sample (The First Look)

The proto sample is your first physical garment. It's made from the fabric you'll use in production, with the construction methods your factory will use. This is where you see if your design translates from 2D to 3D.

What to Check on a Proto Sample:

What to Send Your Factory for the Best Proto:

  1. A tech pack (or detailed spec sheet) with measurements
  2. Reference images or a physical sample to match
  3. Fabric swatch or specification (fiber, GSM, finish)
  4. Color reference (Pantone TCX or physical swatch)
  5. Hardware specifications (button size/color/material, zipper type/length/color)
  6. Labeling and packaging requirements
Factory tip: The #1 cause of proto sample revisions is incomplete specifications. If your tech pack says "red button," we'll choose a red button — but it might not be the red you imagined. "12mm faux-horn button, dark burgundy, 4 holes" gets it right the first time.

Round 2: Fit Sample (The Adjustment)

After you approve the proto (or approve with minor changes), we produce the fit sample. This incorporates any adjustments from the proto round and focuses on getting the sizing right.

What to Check on a Fit Sample:

Common mistake: Brands skip the fit sample to save time. Don't. A proto sample that "looks right" can have measurement errors that only show when worn. The fit sample catches these before 1,000 units are cut.

Round 3: Pre-Production Sample (The Final Check)

The PP sample is produced using the exact fabric from your bulk order, with the exact pattern and construction that will be used for mass production. This is your last chance to catch issues before committing to a full run.

What to Check on a PP Sample:

Factory tip: Always approve the PP sample in writing (email or WhatsApp message). "Approved for production" is the magic phrase. This creates a reference point if there's any dispute later.

How to Avoid Sampling Delays

Sampling typically takes 2-3 weeks for all three rounds. Here's how to speed it up:

1. Send Complete Specifications Upfront

Every missing detail (button size, label placement, hem width) adds a revision cycle. A complete tech pack can get you to approval in Round 1.

2. Be Available for Feedback

When we send photos of your proto sample, we need feedback within 24 hours. Every day of delay extends your timeline by one day. Designate one person as the approver — not a committee.

3. Use Stock Fabrics

Custom-milled fabrics add 2-3 weeks. Stock fabrics (available in our library) can be sampled immediately. For first runs, choose stock — you can always custom-mill later.

4. Don't Over-Revise

Some brands revise endlessly, chasing perfection. Accept that the first production run won't be perfect — it needs to be good enough to sell. You can always iterate in the next season.

5. Batch Your Feedback

Instead of sending one comment at a time, compile all feedback into a single comprehensive list. This lets us make all changes at once, rather than revising the sample 5 times.

Sample Costs: What to Expect

Many factories charge for samples — and this is normal and fair. The cost covers fabric, labor, pattern-making, and the disruption of setting up production for a single garment.

Sample TypeTypical CostRefundable?
Proto Sample$30-80/styleYes — refunded on bulk order ≥300 pcs
Fit Sample$15-40/styleYes — refunded on bulk order ≥300 pcs
PP Sample$15-40/styleYes — refunded on bulk order ≥300 pcs
Shipping (DHL/FedEx)$25-60/sampleNo

At Essty, we refund all sample costs when your bulk order reaches 300 pcs. This means sampling is effectively free for serious buyers.

Conclusion

The sampling process exists to protect both you and the factory. By following the three-round system — proto, fit, pre-production — you'll catch every issue before it becomes a 1,000-unit mistake. The investment of 2-3 weeks and $50-160 per style is negligible compared to the cost of a production run gone wrong.
