Hmmm
Maybe IM young arrogant and cocky but I love wearing a tight fitting shirt showing the pecs and cannons. But get a nice dress shirt from hechts or any store that will look great on you. Most stores carry XL, XXL, since that seems to be the style these days. Look at some of the more urban and hip-hop lines, P-Diddy, Rocawear, Mecca, etc, as they are all baggy and bigger which will be good for you. I have noticed Clairborne makes a nice line that fits well I am about 215 and for a tight look I squeeze into a medium. So check that out, or get some tailoring done.
