European and American clothes size L is domestic XL or XXL. It's basically 1 to 2 yards. Well, I've seen many websites of foreign brands. Their smallest XS size bust is generally above 90 cm, which is as big as domestic S or many M's, mainly because many foreigners are taller, and most importantly, their busts are larger and their shoulders are wider, so especially the American version of clothes are fatter, but there are also slim ones, which are similar to domestic sizes. That is to say, L's European and American clothes are basically 180 or 185.
