It may be one of the biggest fashion events of the year, but even the stars at the annual Met Costume Institute Gala suffer some unfortunate wardrobe choices.

The biggest stars of movies, music and television will hit the red carpet tonight at the New York Metropolitan Museum of Art for the fashion fete.

Tonight's guests include fashionistas like Sarah Jessica Parker, Gwyneth Paltrow, Dakota Fanning, Lana Del Rey, Jessica Alba, Hilary Swank, Kate Upton, Rosie Huntington-Whiteley, Scarlett Johansson, Gisele Bundchen, Kristen Stewart and Cameron Diaz.

But before we see the sure-to-be-stunning looks they're wearing later, let's take a look back at some of the Best and Worst looks from years past.

While Jennifer Lopez, Blake Lively, Beyonce Knowles and Jessica Alba almost always impress, not everyone is as immune to red carpet disasters.

Check out our picks above ... and be sure to come back around 4pm PT for this year's best photos!
