Chinese 75A is roughly US 34A. The 75 means under-bust in centimeters, and the A cup transfers directly.
Chinese 80B is roughly US 36B. If the listing's cup looks shallow, compare the product chart and consider one cup up.
Chinese 85C is roughly US 38C. For sports bras or wire-free styles, brand sizing can be more flexible than wired bras.
Wrap a soft tape snugly (not tight) around your ribcage, directly beneath the bust. Read in centimetres. Round to the nearest 5 — that's your CN band (70, 75, 80…).
Wrap the tape around the fullest part of your bust. The difference between bust and under-bust gives your cup: roughly 10 cm = A, 12 cm = B, 14 cm = C, 16 cm = D.
