Designed for those occasions when you’re going somewhere a bit posh, so you decide to wear a ladylike pencil skirt and heels, but then decided that you really, really want to show your naked ass to everyone you walk by, Prada bring us this black skirt, complete with "Butt Window".  We’re immediately declaring this to be a Crime of Fashion of the highest order. But we’d like to thank Prada for the laugh it gave us when we first laid eyes upon it.

Also: does it look to anyone else like the model in this picture is crossing her fingers, thinking "Dear Lord, I hope The Fashion Police don’t arrest me in this"? Or maybe that’s her middle finger, and she’s planning to stick it in Miuccia’s face as soon as she steps off that runway…
