Streetwear Sample QC Checklist: How to Approve a T-Shirt Before Production

A sample is the last inexpensive place to find an expensive problem. Before an independent clothing brand approves a production run, the sample should be checked against a written specification—not just judged by whether it “looks good.” Save this checklist and use the same process for every sample.

Streetwear sample QC scorecard

Score each category from 0 to 2: 0 = reject, 1 = revise, 2 = approve. Eight categories create a 16-point internal score. This is an ii syndicate workflow tool, not an industry certification.

• Garment measurements
• Fit and silhouette
• Fabric and hand feel
• Construction
• Print or embroidery
• Color consistency
• Wash performance
• Labels and packaging

Internal approval rule: do not approve a sample with a zero in any category, even if its total score is high.

1. Measure the garment

Record actual measurements

• Body width / chest
• Body length
• Shoulder width
• Sleeve length
• Sleeve opening
• Neck opening
• Hem width

Measure the sample using one consistent method and compare the numbers with the approved spec. Photograph the tape placement so the factory, printer or future team member can repeat the measurement.

2. Evaluate fit and silhouette

• Does the shoulder sit where intended?
• Is the body appropriately cropped, standard or elongated?
• Does the sleeve shape match the concept?
• Does the garment hang correctly from front, side and back?
• Does the intended size still work after washing?

For a deeper explanation of fabric weight terminology, use the T-Shirt Fabric Weight Guide.

3. Inspect fabric and construction

• Check fabric weight and hand feel against the approved sample or specification.
• Inspect seams for skipped stitches, loose threads and visible puckering.
• Check neck rib recovery and shape.
• Compare left and right sleeves for symmetry.
• Inspect hems, side seams and reinforcement points.

4. Inspect the decoration

Printed graphics

• Confirm artwork position and dimensions.
• Check edges and small details.
• Look for unintended cracking, pinholes, banding or color shifts.
• Confirm the print does not distort beyond the intended effect when worn.

Embroidery

• Check placement, thread color and overall dimensions.
• Inspect small lettering for legibility.
• Look for puckering around the stitched area.
• Inspect the inside backing and wearer comfort.

Choosing the decoration method earlier in development can prevent avoidable revisions. Compare common options in Screen Printing vs. DTG vs. DTF vs. Embroidery.

5. Run a controlled wash check

Follow the garment's intended care instructions and document the before-and-after condition. Re-measure the same points, photograph the graphic and note changes in fit, surface, color and decoration. Do not advertise a specific shrinkage percentage or durability claim unless your own testing supports it.

6. Check labels and packaging

• Brand label correct
• Size label correct
• Care information correct
• Hangtag correct
• Barcode or SKU correct if used
• Packaging size appropriate
• No old artwork, placeholder copy or incorrect URLs

What happens after approval?

Sample approval should lead into pricing, campaign production and launch planning. Use the Streetwear Drop Profit Calculator before committing to quantities, then map the release with the 8-Week Drop Timeline.
