115 cm Bust Bra Size
A 115 cm bust (≈ 45.3″) is not one size: the cup depends on the underbust. Slide to yours; the table shows every size a 115 cm bust can be.
My bust is 115 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.
