Disclaimer

Every size this site calculates is a starting point for fitting, not a guarantee of fit. Bodies vary in shape as much as size, brands cut the same label differently, and the final judge is always the garment on the body passing physical fit checks. Use results to walk into a fitting room informed, not to skip the fitting room.

Conversion values reflect published sizing conventions and common brand practice. Individual brands deviate, sometimes deliberately; their own charts supersede ours for their garments.

Nothing on this site is medical advice. Breast pain, skin changes, new asymmetry or any health concern belongs with a qualified clinician. A sizing site can tell you a band number; it cannot examine anyone, and it does not try to.
