Shopping for lingerie online can feel like decoding a secret language—especially when you're staring at size charts with letters, numbers, and symbols that make zero sense. If you’re in China or shopping Chinese brands but used to US and EU lingerie sizing, things get even trickier. Don’t sweat it—we’ve got your back (and your bust).
Chinese lingerie sizes follow a unique system based on centimeters and body measurements, while the US uses band and cup letters (like 34B), and Europe leans toward pure centimeter-based codes. Confusing? Yes. Solvable? Absolutely.
How Chinese Sizing Works
In China, bra sizes are labeled as “80A,” “75B,” etc. The number represents the underbust measurement in centimeters (your band size), and the letter is the cup size—just like in the West. But here’s the catch: Chinese brands often run smaller, and their cup volume progression isn’t always consistent with US/EU standards.
For example, a Chinese 75B doesn’t always equal a US 75B. In fact, due to differences in how brands cut their bras, it might fit more like a US 34A or even a 32B depending on the manufacturer.
Quick Conversion Table (Chinese to US/EU)
| Chinese Size | Band (cm) | Underbust (inches) | US Equivalent | EU Equivalent | Cup Volume Note |
|---|---|---|---|---|---|
| 70A | 70 | 27.6 | 30A | 70A | Slighter cup volume |
| 75B | 75 | 29.5 | 32B / 34A | 75B | Often runs small |
| 80C | 80 | 31.5 | 34C | 80C | Most accurate match |
| 85D | 85 | 33.5 | 36D | 85D | Check brand fit guide |
As shown, band sizes often align closely between systems, but cup sizing? Not so much. That’s because cup volume increases vary by region. In the US, each cup letter adds about 1 inch (2.54 cm) of difference between bust and underbust. In China, the jump can be less consistent—sometimes as little as 2 cm per cup, leading to tighter fits.
Tips for Accurate Sizing
- Measure Yourself: Wrap a soft tape around your ribcage (underbust) and fullest part of your bust. Subtract underbust from bust—each inch ≈ one cup size.
- Go Up a Cup: If you wear a 75B in China, try a 34B or even 34C in US brands for a comparable fit.
- Check Brand Charts: Always consult the specific brand’s size guide—especially when buying from international lingerie labels.
Remember: A well-fitting bra shouldn’t dig, spill, or ride up. It should feel like second skin—supportive, seamless, and sexy.
So next time you're eyeing that lace set from a Shanghai boutique or a Parisian corset online, don’t guess. Measure, convert, and conquer. Your perfect fit is out there—it just speaks a slightly different language.
