I like this look because she's wearing all simple, basic pieces and I think that's a quintessential definition of style. It's something I'd do.
Her inspiration: Alexander Wang Fall 2008, the collection itself inspired by Wang's muse, the off-duty model.
Some clips:

(the second to the right is the outfit she was remaking) I liked the show because of the bold statement of the exposed zipper (1st and second outfits), the color palette throughout the collection and the use of menswear as womenswear. It also had a very torn, worn out "deconstructed chic" feel to it, no? Very fitting for America's current economy.... (i.e. the Recessionista)

The designer and Erin Wasson of RVCA (she's a designer and I think a model too) she styled this show.
