Fab or flop: Olivia Palermo's sporty pants, Diane Kruger's lace tights and more

Paris Fashion Week was upon us this week, and while some stars wowed in head-turning fashions while hopping from show to show and fêteing in the city of lights, others missed the mark.

Olivia Palermo was among those who hit some serious high notes. The former reality star-turned-street syle darling wowed in two notable looks: one super-luxe, ultra cool ensemble that consisted of navy, bootcut-slacks with sporty yellow stripes down the sides and another schoolgirl-esque plaid minidress.

While Palermo mix-and-matched in an effortlessly-cool way, Diane Kruger, who typically rocks stunning styles, disappointed in an overwhelming combination of patterns and prints. The actress paired a tweed, striped minidress with intricate lace tights -- and while we love the pieces separately, they didn't quite mesh.

While not in attendance at PFW, actress Amanda Peet wowed us with her gorgeous look on the "People v. O.J. Simpson" red carpet. These days, premieres are laden with slinky cleavage and ab-baring numbers, but Peet looked chic -- and covered up -- in a stylish plaid skirt, black sweater and black brogues. A black topcoat slung over her shoulders and metallic clutch elevated her fab look.

Click through the slideshow above to see celeb styles this week that were absolutely fabulous -- and others that totally flopped.
