Celebs: we love to ooo and ahh over their style just as much as we love to loathe their fashion taste. One week they're looking completely fab, and the next week they're a total flop. Unless you're Olivia Palermo, who's been hitting it out of the park with spot-on style every week.

As for the likes of Anne Hathaway, who's blowing us away with her billowing pants, and Demi Lovato's haute ranch couture, not every celeb can look super-fabulous all the time.

We will give props to one celebrity in particular, Amanda Bynes, who's finally found a colorful new wig that works for her.
