Since I've factored a Gossip Girl addiction into my weekly schedule, Mondays miss their dose of drama. We've come to see routine looks from the leading ladies on this show . . . but while some styles barely change, others are regular beauty chameleons. Check out pictures I've rounded up thus far to tide us over until tonight's episode. To be fair, we'll only look at apples to apples — so you don't need to reveal your Team Serena or Team Blair affiliations here! Ready, set, start the slideshow now!
