Plaid on Plaid

Did anyone catch B's plaid on plaid outfit on Gossip Girl this week? I've been a little slow to post on it because I'm out in Cal, but I just had to post on it! Especially because I think it's interesting how this is a trend from the D&G runway from their fall and winter collection (showcased here in who what wear tv: http://www.whowhatwear.com/website/full-article/runway-to-real-way-dg/ )
So here's why I'm thinking this is interesting: is Gossip Girl a bit behind this trend? Or is it just playing it now because on the show it's supposed to be winter and it's a winter trend? Or since Spring clothes will be hitting the stores in about two weeks, probably less, should they be heading into spring '09 trends? I know that the episode was filmed pretty recently, and clearly plaid has made quite a comeback for both fall and winter, but as a show who has fashion basically as a main character don't you kind of expect them to be a bit more ahead of the fashion curve?
Note: I couldn't find a picture of the plaid on plaid ensemble, but she did wear plaid clothes almost the entire episode (You've got Yale if you are going to download it from itunes)
