Keep the shirt on! She’ll find another girlfriend in no time!
Aaaand there’s a double standard: If a guy wore that shirt, everyone will be thinking he’s a bastard to be with, good for her she left him!
If a lady wore that shirt, I’d be thinking, “Maybe I’d have a shot at her, too.”
IF a shirt like that is for real, I’d buy it! XXXXXL! Because, hey, a shirt like that should fit two like-minded people.
