Oscar's Red Carpet: 2010's Worst Dressed Stars

It's the biggest night in Hollywood, when fashion and cinema meet at the most glamorous red carpet of the year. Some stars played it too safe, while others took risks that just didn't pay off. Check out our picks for the worst looks of the night so far.  (AP)

The 'Inglourious Basterds' starlet looks like she crafted her bulky frock from tissue paper. (AP)

We feel for Molly. The Cleopatra hair (wig?) and matching waist & arm jewelry make this an unfortunate ensemble. (AP)

Really, Penny? The Best Supporting Actress nominee's crimson number is just so... predictable.  (AP)

There are no words to describe this unfortunate choice. Breast buds?!? (AP)

Maggie's watercolor-inspired frock was a bit casual for the Oscar's, no? This colorful look would have been better at a summer wedding. (AP)

This gown is just so complicated. Somewhere under all the lace, appliques, jeweled belt, tulle, and ruffles lies a perfectly acceptable dress. (AP)

Miley's gown is gorgeous, but at 17, the star is too young for such a low-cut look! And the bikini tan lines don't help matters. (AP)

SJP's Chanel frock drew raves on the carpet, but maybe the concept is over our heads because it kind of just seems like an embellished sack. (AP)

Noooooo! The waist-high slit is over-the-top, even for a sexy diva of Ms. Carey's caliber. It's legs OR cleavage, Mariah! (AP)

This strange white creation looks like a wedding dress the Jetsons would approve of. No no, J. Lo. (AP)
