For more than a decade, Khanh Linh has translated biometric data and textile science into lingerie that actually fits real bodies. She has led fit-development and production hand-over for 850+ bra and brief styles across Asia-Pacific and Europe, partnering with mills to refine everything from low-gauge powernet to biodegradable lace. At UnderwearIQ she audits pattern blocks and wear-trial data to keep our “IQ Score” grounded in engineering reality rather than marketing hype.

What Linh Covers on UnderwearIQ
- “Fit Clinic” Series – Explains why quad-boob, band ride-up, and muffin-top happen, plus data-backed fixes
- Fabric Myth-Busters – Does “seamless” always mean chafe-free? Is recycled nylon weaker?
- Behind-the-Label Audits – Breakdowns of factory certifications, chemical management, and worker wellbeing for popular lingerie brands
Research & Design Philosophy
“True comfort is where fabric physics, pattern geometry, and the wearer’s lived experience intersect. Measure all three—or redesign until they align.”
