This is worthy of being a separate thread. My "new" vintage Burberry rain coat - age unknown (though shell 67% polyester, 33% cotton, lining 50/50 if that helps in dating it) - has a tab inside a pocket saying "44 REG." Burberry's current website relates their 44 coat to an "XS" (i.e. "extra small)" yet my coat seems like about a medium or 38-40 U.S. size. Is something missing here? Has Burberry changed its size definitions over the years?
