Notes by category

Ordered by what to check before buying — not by popularity.

1Sneakers

Good for: Hype pairs, runners and daily trainers.

Confirm: Exact EU/US size, colourway code, and box/accessories.

QC focus: Stitching around the logo, midsole paint, and the size tag.

Trap: Ordering your usual size — China sizing often runs small; measure and check the seller's chart.

2Jerseys

Good for: Football, basketball and retro sports jerseys.

Confirm: Team, season, and the name/number print; fan vs player fit.

QC focus: Badge and sponsor logos, stitched vs printed numbers, and the mesh fabric.

3Hoodies

Good for: Heavyweight, boxy and graphic hoodies.

Confirm: Fit (oversized vs true-to-size) and GSM/weight if listed.

QC focus: Print alignment, drawcord tips, and cuff ribbing.

Trap: Chasing a 'trending' drop without reading the weight number — light and heavyweight feel very different.

4T-shirts

Good for: Basics, boxy tees and printed shirts.

Confirm: Length and shoulder width, not just S/M/L.

QC focus: Print edges, collar rib, and hem stitching.

Good for: Fragrances, gift sets and testers.

Confirm: Bottle size in ml and concentration (EDT vs EDP).

QC focus: Seal, cellophane wrap, cap fit, and label print.

6Jeans & pants

Good for: Denim, cargos and trousers.

Confirm: Waist in cm and inseam length.

Browse
