85 cm Underbust Bra Size
A snug 85 cm underbust (≈ 33.5″) is a US 34 band, labelled EU 75 and FR 90. Slide to your bust in cm for the cup.
My underbust is 85 cm: what's my size?
Why the EU label isn't your centimeters. An 84 cm underbust is a US 34 band, which the EU labels 75: the label follows US × 2.5 − 10, not the raw reading. That is why a converted size can feel a step off from a bra drafted natively in EU sizing.
