It's not unusual for embarrassing clothing (or shoe!) [1] malfunctions to happen on the runway. For this poor model, it's one of those days. What's even more disturbing is the camera dude's instinctive urge to zoom in when the chick is trying to run out of sight. A close-up of the model's arse is need-to-see "news," eh? Thanks, College Humor [2]!
