Taylor Swift Wardrobe MalfunctionWhoops.  I guess that wasn’t supposed to happen.

Some Taylor Swift fans in St. Louis got a little more bang for their buck on Saturday than they expected.  While singing “You Belong with Me”, the bottom of Taylor’s dress flew up thanks to a wind machine, exposing her panties to thousands of appreciative fans.

Switft, being the professional that she, didn’t even bat an eye.

Well done, Marilyn, er, Taylor.
