I'm about the same and taper down to a 32-33" waist, went with a M. It loosens up a bit and the length is perfect. It's fitted but not tight or anything.
Well I didn't come across a post of someone who is 6'0, 177 lbs and a 42 chest. (maybe its there and I just missed it) I figure maybe someone could benifit by me posting my findings...I didn't think it was a big deal but I suppose.
