Sizing Tips

Underwear sizing follows hip measurement more than waist. Asian sizing typically runs one size smaller than US/EU equivalents. Elastic recovery is more important than initial stretch.

Material Guide

Cotton blends should feel soft, not coarse. Modal and bamboo fabrics have natural breathability. Synthetic blends should list elastane percentage for stretch recovery.
