Haven't noticed so much of that here in Europe.  When it comes to unsized things I'm always a size S for Small. When it comes to shirts/jeans/suits and "proper" clothes everything is measured in inches.  Men don't have to deal with sizes the same way women do for their outfits.  (All the women in my life would significantly prefer dresses/skirts/etc to be sized in CM/inches.  Precisely to avoid vanity/fake-measurements.)
