Great construction and material thus far.  I'm not thin by any means but my body is not shaped like a bell.  My chest is 50 and my waist is 38.  I ordered a 52 as my shoulders are wide.  The 52 fits my shoulders perfect but I have gobs and gobs of extra material around my waist.  I think I'll just have the sides taken in 3 inches on each side and then it will be loose but not hugely so.  It would be nice if they allowed such things as Chest XL, L, M, S  and waist XL, L, M, S.
