Underwear is a practical category on the OopBuy spreadsheet that experienced buyers use as low-risk test orders. In 2026, boxer briefs and functional underwear dominate requests. Key QC areas include waistband elasticity, fabric breathability, and leg-grip quality. Because these items are worn daily, material comfort matters more than logo accuracy for most buyers.

Buying Tips for Underwear/Underpants
Check the waistband recovery
Stretch the waistband in QC photos and watch if it snaps back. Weak elastic loses shape after a few washes.
Ask for fabric composition
Cotton blends with spandex or modal feel better and last longer than 100% cotton, which loses softness after repeated washing.
Inspect leg grip bands
The inner leg bands should be soft and wide. Narrow or rough bands roll up and cause irritation throughout the day.
