I needed a tuxedo to wear at my Masonic Lodge and this tuxedo fit the bill perfectly, I first ordered a 48reg but I wear a 48 regular in an Executive Cut (Portly) I am 5'11" 245 lbs and the tux was too small so I sent it back which went smooth, and re-ordered a 54Regular thinking I would get it altered to fit, well too my surprise along with my wife's it fit perfect I just had to get the pants hemmed. I usually wear a 40/32 but the pants that came with the tux were a 44/32 also fit perfect. Moral of the story; if your like alot of over 50 men that developed port go higher in size.
