One of the best things about the show Gossip Girl is the characters attend a fancy private school that requires the show's stars to wear school girl uniforms. Naturally, they hike the skirts way up and leave a few shirt buttons undone - actions that would most likely be reprimanded in a real school, but for television it works out great.

Here's Blake Lively showing off her lovely long legs while posing in her uniform for a promotional photo shoot for the show, plus a few behind the scenes pictures to boot. She could walk right off the set and go out for Halloween without even changing.
