Who This Category Is For
Bulk buyers, comfort-first shoppers, and anyone wanting quality basics at multi-pack value.
Sizing Guide
Asian sizing runs significantly smaller. Size up 1-2 sizes from your US size. Check waist measurement in cm.
Do This
- Check fabric composition — cotton-spandex blends for comfort
- Verify multi-pack contents in QC photos
- Look for elastic waistband quality indicators
Avoid This
- Do not order without checking waist measurement, not just tag size
- Avoid unknown material batches — skin sensitivity matters
- Skip if no hygiene-seal confirmation is shown
QC Observation Points
- 1Elastic band stitching consistency
- 2Fabric softness and thickness
- 3Seam flatness for comfort
