Why Sampling Exists (And Why You Can't Skip It)

Sampling is not the factory being difficult. It's the only way to verify that your two-dimensional design translates into a wearable, sellable garment before you commit to 200+ pieces.

Every sampling round catches something: a seam that pulls, a sleeve that's too tight, a fabric that drapes differently than expected, a button that's too small to sew cleanly. Catching these at the sample stage costs $50–$150. Catching them in bulk costs thousands.

The 5 Stages of Sampling

Stage 1: Pattern Making (Before Any Sample Exists)

Before fabric is cut, a pattern maker creates the paper or digital pattern based on your tech pack measurements.

• What it is: A set of pattern pieces (front, back, sleeve, collar, facing, etc.) that, when sewn together, create your garment in the base size.
• Timeline: 2–4 days for a simple style; 3–7 days for complex construction.
• Cost: $30–$100 per style (sometimes included in sampling fee).
• Why it matters: A bad pattern means every sample after it will be wrong. This is the foundation.

Stage 2: Proto Sample (Prototype)

The first physical version of your design. Made to test the concept, proportions, and construction logic.

• Purpose: Does the design work as a garment? Are the proportions right? Is the construction feasible?
• Fabric: Often a substitute fabric (similar weight/hand-feel) if bulk fabric isn't ready yet.
• Fit model: Usually made in one size (base size, often M or S).
• Timeline: 5–7 days after pattern is approved.
• Cost: $50–$150 per style depending on complexity.
• What to check: Overall silhouette, proportion, design feasibility, major construction issues.

Common mistake: Expecting the proto to be perfect. It won't be. It's a proof of concept, not a final product. The proto tells you if the idea works — not if every seam is perfect.

Stage 3: Fit Sample

Once the proto confirms the design direction, the fit sample tests sizing, ease, and wearability across (at least) the base size.

• Purpose: Adjust proportions, check ease (how loosely or tightly the garment sits on the body), verify comfort and movement.
• Fabric: Ideally the actual bulk fabric, or a very close match.
• What to check:
  • Chest/waist/hip ease — is there enough room to move?
  • Sleeve mobility — can the wearer raise arms?
  • Length — does it hit where you want?
  • Neckline — does it gape, bind, or sit correctly?
  • Shoulder seam — does it sit on the shoulder point?
• Timeline: 5–7 days.
• Cost: $40–$120 per style.

Pro tip: Try the fit sample on someone with your target customer's body type, not just the slimmest person in the room. If your customer is a size M, test on a size M.

Stage 4: PP Sample (Pre-Production Sample)

The PP sample is the most important sample of the entire process. It is the approved standard against which bulk production will be measured.

• Purpose: Final confirmation of every detail before bulk cutting begins.
• Fabric: Must be the actual bulk fabric (same dye lot, same finish).
• Trims: All actual trims (zippers, buttons, labels, hangtags).
• Construction: Exactly as bulk will be produced — same machines, same operators, same finishing.
• Timeline: 7–10 days.
• Cost: Usually at bulk pricing (since it uses bulk materials), sometimes slightly higher.
• What to check: EVERYTHING. Measurements against spec table, fabric hand-feel, color accuracy, trim placement, stitching quality, pressing, packaging.

Critical rule: Once you approve the PP sample, any changes after that point are considered a new order. Approve carefully.

Stage 5: Size Set Sample

Not always required for small runs, but recommended if you're producing 4+ sizes.

• Purpose: Verify that grading (size scaling) is correct across all sizes.
• What to check: Does XS look like a scaled-down version of M? Does XL have the right proportions, or does it look like a stretched M?
• Timeline: 7–10 days.
• Cost: One garment per size (usually 4–6 pieces).

Sampling Timeline Overview

Total sampling time (typical): 3–5 weeks for 2 rounds (proto + fit). Add 1–2 weeks if PP and size set are needed.

How Many Rounds Do You Need?

For most first collections:

• Simple styles (T-shirts, basic dresses, simple bottoms): 1–2 rounds (proto → fit → bulk)
• Medium complexity (structured dresses, jackets, trousers): 2–3 rounds (proto → fit → revised fit → PP)
• High complexity (tailored jackets, multi-layer garments, draped designs): 3–4 rounds

Rule of thumb: If you're on your first round, you need at least one more. If you're on your second round and the changes are minor (length adjustment, small ease tweak), you might be ready for PP.

Common Sampling Mistakes

• Approving the PP sample too quickly. You have one chance. Check every measurement.
• Changing the design mid-process. Every change resets the clock. Finalize your design before proto.
• Using different fabric for proto than bulk. The garment will fit differently. If you must use a substitute, note it and adjust expectations.
• Not keeping the PP sample. Store it in a safe place — it's your reference if bulk quality is questioned.
• Skipping fit on a real body. A sample hanging on a rack looks different than on a person. Always fit on a body.

How We Handle Sampling

At Sesiy, our sampling process is built around three principles:

• Clear communication: After each round, we send photos + measurements + notes on what changed.
• Sampling fee deductible: Sampling fees are credited against your first bulk order (when order reaches agreed volume).
• Speed: Proto in 5–7 days, fit in 5–7 days, PP in 7–10 days.
