Why measurement-first

A size label is a starting point, not a physical measurement.

ISO 8559-2:2025 defines clothing size designation around body dimensions, while manufacturers decide garment measurements, ease, cut and styling. That is why our fit tools prefer actual measurements and show assumptions instead of declaring one universal S/M/L conversion.

Bras, briefs, boxer briefs, panties, shapewear, camisoles, slips, hosiery, tights, socks, undershirts and thermal/base layers each get dedicated tools and guides—with brand variability warnings and no false precision.
