I once saw a guy at YYZ with a sweat shirt that had deliberately inserted "bear claw" tears in it, and fake blood printed on it. He had nothing under it, so his fat and hairy chest was visible in the slits.

Forget the airport, wearing this anywhere is a bad idea! Even alone at home.

I understand the need for comfort, but if you wouldn't wear it going to the corner store, don't wear it on the airplane. PJs, wife beaters, bear claw sweats, gym shorts..yikes!
