Buying Tips for Underwear / Underpants
Waistband recovery
A good waistband snaps back after stretching and does not fold over during the day.
Flatlock seams
Flat seams reduce chafing and hold up better to repeated washing.
Gusset design
A well-designed gusset adds comfort and reduces strain on the main seams.
QC Checkpoints
| Checkpoint | What to Look For |
|---|---|
| Waistband elasticity | Should return to original shape after repeated stretch. |
| Seam flatness | No raised ridges that could cause irritation during wear. |
| Tag placement | Printed or external tags are preferable for comfort. |
| Fabric opacity | Should not become translucent when stretched over the body. |
Sizing Notes
Most waistbands are forgiving, but leg opening tightness varies by cut. Check the leg opening measurement if you have larger thighs.
Risk Awareness
Elastic degradation is common in budget batches. Consider buying only small quantities for first-time orders.
