Looking to get a suit tomorrow (Alfani Line at Macys). My chest measures 37-38", although the one suit jacket I have, from the same Alfani line, is a 36R. It looks great but does fit a tiny bit snug in the shoulders (albeit not a bad "snug"), but otherwise is fine unless I am doing the "fat guy in a little coat" motion. It also buttons fine. I tried a 38R and while it did give me a bit better range of movement, and was more comfortable, it didnt LOOK as slim and tailored as the 36R. I'm pretty much between sizes. Is it really that important that I have ample mobility? Or do I go for what looks best, and ignore the measurements (chest size and waist drop size) that say I SHOULD be using a 38? As far as pant sizing, does a smaller waist size inevitably mean a slimmer pant leg? I tried on some W30 and some W32. While the 32's fit me perfectly, I much preferred how the 30's fit everywhere else (seat/crotch/etc) besides the waist of course, where they barely buttoned. Would it be wise to buy a W30 and get it let out a bit? Or buy the W32 and alter it? *Pics included to show 36R fit.* Thanks gentlemen I appreciate it in advance.
