true to sizeOrdered a Large at first but was a little snug so exchanged for an extra large and it fits well.The shirt was way too tight. My wife will keep it for herself. Want a XXL but can't find that option :-(Great shirt!! It was a great birthday gift!Go Hoosiers!Great shirt for a fanUgly. Poor Quality. I’mI've put this shirt up to other shirts of my husband's and it's much narrower in the belly area. Cut like a collegiate shirt which is generally 1/2 to 1 full size smaller than adult size.high quality shirt.
