BoO suiting is good quality. IIRC, they are made by Martin Greenfield in NYC and are fully canvassed. I have found them to be cut short, but not overly skinny (i.e., not a huge drop). High armholes might be difficult for you if you're buff.
I have a suit, that I just wore to a wedding and could post pictures in, but I'd agree with the above post, they're very nice but it's definitely tight in the arms, but I wear the same size I do in shirts (3 in both).
