I dunno. Got fitted by some stupid whore for my tux. 48 fits arms / shoulders and chest, but I could put like 3 basket balls under there. Filmy said to get a 44 and just relax because I'll only be wearing it for a short time. I think I could rip the 44 if I coughed really hard but it will look better. STupid cunt that fit me for it was like "golly the problem is that you're so big up here and not down here" Me = "I think your parents are related"
