Fashion Flashback: The Worst Dressed at the 2011 Oscars (PHOTOS)

The Oscars signal the end of awards season — saving the best for last! Unfortunately, the best doesn’t always make its way down the red carpet. In anticipation of Sunday’s big show, Celebuzz has picked up the pop culture remote for a fashion rewind!

Celebuzz fashion expert Art Conn gave us his worst dressed list — presented in the gallery above. From some usual fashion icons such as Nicole Kidman and Hilary Swank, to people who were just a little too casual for Hollywood’s biggest night, Art played fashion police with some arresting commentary on his picks for worst dressed.
