Use this reverse lookup when a Chinese lingerie listing asks for a centimeter band such as 70, 75, 80 or 85.
Quick answer: US 32A is about Chinese 70A, US 34B is about 75B, US 36C is about 80C and US 38D is about 85D.
Start with Chinese 75B, then check the seller's under-bust range.
Start with Chinese 80C and confirm the bust difference in centimeters.
This is an estimate, not a brand guarantee.
Chinese listings may use EU-style centimeter bands.
This page answers one specific size search intent. For the best fit, start with the linked main converter and use the centimeter measurements on the Chinese chart whenever they are available.
Marketplace labels are useful shortcuts, but brand charts, garment type, fabric stretch and body measurements can change the final fit. Treat the lookup as a nearest match, not a guaranteed size.
Chinese size labels are practical lookup shortcuts, not universal brand guarantees. A CN shoe label, clothing size, bra code or Taobao chart row can vary by seller, product category, last shape, fabric stretch and whether the chart shows body measurements or garment measurements.
When possible, use the centimeter value first: foot length for shoes, bust/waist/hip for clothing, under-bust and cup difference for bras, and the specific Taobao chart row for marketplace listings. Then use the converter result as the nearest US, UK or EU match.
