Okay, everybody - I need your help!!! Can someone please tell me what epsiode these images are from? Thanks***

Santana wearing that clothes at s02e13 - Comeback, but i can't find that scenes. Sorry :/

Actually it's not an episode, it's from the Chevy commercial :

Though I think they shot it at the same time they shot Comeback, since they're all dressed the same as the picture Gleek_8 posted
