I am by no means a big person, I'm only 5'7, just a human man. That being said, I followed the recommendation to by a size up, perfect fit. It would behoove you to follow their recommendation, or dont, and then just blame Brooke because everything is her fault.
This is a great shirt and a great fit! Everyone asks where I bought it.
All items were great quality. My sons loved them.
I literally added 30 lbs to all my max lifts, impregnated my wife, and wrestled an alligator after putting this shirt on. User discretion advised.
