I've been looking for a 38R or slim 40R tuxedo for ages. SB, 1 button, Peak lapel, you know the drill...nothing decent comes up on Ebay or here. If it does, it's every third month. However, I see that Jos. A Banks are selling tuxedos like that for 200 bucks, on sale now. Even in wool (most 100-200$ tux on ebay are Poly), just can't seem to find any better deals than that. Especially not brand new. Anyway, I'm usually a slim. 38R to Slim 40R. Narrow/18-18.25'' shoulders. Any idea if I should size down on JAB? I've hear so many horror stories around here on their boxy old-man cuts.
