Not to be rude, but you are far from my definition of athletic. I consider myself reasonably athletic and had to get CT slim-fit shirts taken in ~4 inches at the waist. However, I agree with the last poster, if you tuck a little differently the fit issues in the waist might disappear. The chest does look a little small, but nothing too bad if you're used to it (and don't mind "showing off" your chest).
My two cents at least
