Chinese bra size help!

[Yogayogayoga]

I bought a bundle of women's clothing to sell on Vinted. There are some lovely bras inside but the sizing is Chinese and I'm getting conflicting information on Google regarding conversion. Can anyone tell me what these sizes are in UK?

C90
C75
A80
B80
B85

I'm assuming they are Chinese, but could well be from somewhere else. I've including a pic of the label of one of them.

The letters will be the cup size and the number in cm instead of inches so just convert it. For example an 85 is around a 36 Uk size

I agree, the numbers may be in cm so divide by 2.5 for the approximate size in inches. However, I'd measure them to be sure and but the actual measurement in the listing and tell potential buyers to compare with measurements of bras they already have.

As for the cup size, they may follow UK convention, they may not and cup size isn't definitive anyway. If they're made for the Chinese market, I'd expect them to be smaller than those designed for the UK as Chinese women tend to be of smaller build than average UK women.

Unfortunately, how ever lovely they are, unless they're a recognised brand, it might be difficult to sell them for a decent price, because people won't know what to search for and there must be thousands of bras on Vinted and people would generally only search if they're looking for a known size in a particular brand.
