Shopping for bras in China

Chinese domestic sizing prints EU-style centimeter bands with cup letters that follow the Japanese-style fuller convention in many brands: a 75B from a domestic label often fits like an EU 75A. Taobao listings mix conventions freely, so measurement charts beat printed sizes.

Urban brands like Neiwai and Ubras have made wireless one-size-stretch styles enormous; they fit average volumes well but under-support beyond a D equivalent.

Brands you will commonly see: Neiwai, Ubras, Aimer, Embry Form.

China follows the same EU arithmetic as every other EU market, so the conversion chart lives in one place rather than being repeated: the full EU conversion chart. Sizes are written band first, then cup, as in 75E.

Frequently asked questions

What bra sizing system does China use?
China primarily uses EU sizing conventions in mainstream retail, though imported brands can carry other systems' labels. The calculator above highlights your EU size and shows all 7 systems for imports.
Which bra brands are common in China?
Commonly available names include Neiwai, Ubras, Aimer, Embry Form. Local availability shifts, and each brand's own centimeter chart beats any converted label when they disagree.
What is a US 34DD in China sizing?
A US 34DD is a 75E in China. The same bra is a UK 34DD and an EU 75E, because the cup ladders diverge after D.
Do I add inches to my underbust measurement in China?
No. The old habit of adding four or five inches was written for non-stretch fabric and produces a band about two sizes too loose on a modern elastic one. Measure snug and level, and use that number directly, whichever system the label uses.
