Here's what nobody in the underwear industry talks about straight: the wedgie is a geometry failure, not a sizing problem. The whole category has spent decades telling women to size up, try different cuts, buy this brand instead — and nobody actually solved the underlying mechanics. We build underwear at our Shantou factory, and when we started engineering around thigh-to-leg-opening geometry instead of waist-based sizing, the complaints stopped. This is the guide we wish existed when we started.
