Mens clothes sizes vary widely depending on country of origin. be aware that many clothes are now made in China and are sized for people of Asian/Oriental ancestry. “Large” in fact means those who are short and fat – such as middle aged Singapore businessmen.
BTW I managed to slim back down to medium size in the end after that infamous Hong Kong suit that poly found (and even he found the trousers were one size wrong). Having never tried or considered crossdressing I have no idea if the same occurs with ladies sizes – I would be “too old and hairy” by the standards of SE Asia anyway.
