why would you have to wear another shirt underneath? i think it'd be a great look. at least for a cool guy like me. somebody buy me a reds jersey and ill post pics. Because it would look weird without a shirt, cool guy or not. WELL we had sleeveless jerseys for baseball my freshman year. one time we all wore them to a game, and all the ladies in the house said yeah, but the umpire said no, so we had to wear shirts under them. but they were still cool. Hah, okay. But I'm sure there some people who just couldn't pull it off.
