This Week's Worst-Dressed List Features Vanessa Hudgens' Animal Fur Hat (PHOTOS)

This week's worst-dressed list saw busy dresses and a little too much volume. Both Rita Ora and Kelly Osbourne struggled to make a prints work on the red carpet, as they made the cardinal mistake of over accessorizing. Meanwhile, Marion Cotillard wore a drop crotch jumpsuit that created extra bulk in her nether regions.

Though this week was a hotbed for sartorial missteps, Vanessa Hudgens' neon spandex, animal fur hat and crop top takes the cake for the most outrageous look. The "Spring Breakers" star's daring fashion ensemble is best reserved for Halloween.

Check out those over-the-top looks, as well as more celebrities who made our week's worst-dressed list. Do you agree with us?
