Hi, I'm looking for a way of finding the correct sizes for bras and their cup sizes for manufacturing them in China for several different markets. It's been quite hard to get this information as all brands seem to have different sizes, so any help here would be highly appreciated!
There is an Israeli company/startup that specialized in this - Brayola - they recently got sold to another company (try Google them) - partnering / using their service would be one of your best options because otherwise you have to create your own system/technology which is both costly and time consuming because (as you said) each company/country has it's own sizes.
I've successfully helped over 300 entrepreneurs, startups and businesses, and I would be happy to help you. After scheduling a call, please send me some background information so that I can prepare in advance - thus giving you maximum value for your money. Take a look at the great reviews I’ve received: https://clarity.fm/assafben-david
There is a way to get information about measurement systems of these countries and use it for setting sizes
