On again/off again friends Britney Spears, Paris Hilton and Lindsay Lohan not only have similar partying styles but apparently all have the same poor sense of fashion as well. While Britney and Paris tied for the #1 position on Blackwell's worst dressed list, Lohan wasn't far behind. Lindsay rounded out the top 3 with her oversized sweatshirts, tights and ridiculous 70's inspired fashion.

While Spears, Hilton and Lohan found themselves on the poor end of Blackwell's list, some other superstars like Beyonce, Kate Winslet and Angelina Jolie were praised for their great style sense.

Some of the other celebrities making the worst dressed list include music sensations Christina Aguilera and Mariah Carey. All of the women on the worst dressed list seem to have somewhat provocative styles that don't leave a whole lot to the imagination. Someone should tell them that less is not more when it comes to fashion.
