Stop guessing on sizes. Our detailed conversion charts and brand-specific tips will save you from fit disasters on every order.
Size mishaps are the #1 reason for returns in the rep community. Asian sizing runs significantly smaller than US, UK, and EU standards. This guide provides conversion charts, measurement techniques, and brand-specific quirks to ensure every item you order fits perfectly.

How to Measure Yourself

Brand-Specific Sizing Quirks
| Nike Tech Fleece | Runs slim; size up once |
| Supreme hoodies | True to Asian size; boxy fit |
| Essentials | Oversized; stick to your Asian size |
| Travis Scott merch | Oversized; size down if between sizes |
| Amiri jeans | Very slim; size up once |
Shoe Sizing Deep Dive
Shoe sizing is the trickiest because Asian shoe sizes don't always align with US sizes linearly. For Nike Dunks, many buyers go true to size. For Yeezys, half size up is common. For New Balance 550, true to size works for most.

Frequently Asked Questions
What if the seller doesn't provide a size chart?
Message the seller via WeChat or the platform chat. Most Weidian sellers respond within 24 hours with detailed measurements.
How do I measure inseam on pants?
Lay the pants flat and measure from the crotch seam to the bottom of the leg. For rep pants, add 1-2cm to your measurement for shrinkage after washing.
Do rep shoes fit the same as retail?
Top-tier batches usually fit very close to retail. Budget batches may have slightly narrower toe boxes. When in doubt, half size up.
