We can learn a lot about crimes of fashion and how to avoid them by observing Britney at work. Brit, you see, is a seasoned fashion criminal: she’s done the crime(s), she’s done the time (marriage to K-Fed was punishment enough, we feel), and now she’s doing it all over again, this time with accomplice Paris Hilton – an occassional fashion criminal herself.

Paris, though – Paris has cleaned up her act, lately. In fact, I’d even go so far as to say that Paris has been looking good lately. In this picture, f’rinstance, we can see her trying to stop Britney. Paris knows what’s about to happen. She knows Britney done forgot to wear underwear again. And she knows that Britney? Is about to show us all her bare ass – back and front. Pictures are after the jump – but beware, these are NOT work safe…

What did we learn about fashion from this? Well, a lady should know how to get out of a car without flashing her ass for one. And if you’re going to be wearing a skirt as short as Britney’s? Don’t forget your underwear…
