Who This Category Is For
Everyday wear buyers, graphic tee collectors, and anyone wanting quality basics without the retail markup.
Sizing Guide
Most batches run true to size. For oversized fit, go up one size. Check chest width and length against your favorite tee.
Do This
- Check GSM — 220-260GSM for heavyweight, 180-200GSM for summer
- Look at collar ribbing quality in QC photos
- Verify print method: screen print lasts longer than DTG on reps
Avoid This
- Do not buy the cheapest batch expecting premium thickness
- Avoid white tees from unknown batches — translucency is common
- Skip if the size chart has no shoulder width measurement
QC Observation Points
- 1Print placement centered and level
- 2Collar shape symmetry after washing simulation
- 3Fabric weight consistency across the shirt
