The 2011 Teen Choice Awards proved that young Hollywood stars like Emma Stone, Blake Lively and Selena Gomez are just as stylish and sophisticated as their more established counterparts. However, not every celeb who attended Sunday night's show was a universal hit with their fans and fashion critics.

Tyra Banks may still have the physique of a swimsuit model, but the 37-year-old talk show host wore an unflattering black-and-yellow strapless leather Thierry Mugler design that had many people on Twitter referring to her as "catwoman."

"Hey there boo! On my way to Teen Choice Awards. Rockin' black leather and gold! Kinda like a fierce bumble bee!!!" Banks tweeted earlier in the day.

Fergie embraced the same bold color combo, stepping out in a long-sleeved star print Dolce & Gabbana minidress with studded Christian Louboutin pumps. And while the 36-year-old singer's dark roots are intentional, the high-contrast hair color is tricky for anyone, even the princess of the Peas, to pull off.

While her sister Kim played it safe in a black and white Givenchy ensemble, Kourtney Kardashian, 32, opted for a bright cobalt-blue strapless Blaque Label dress with an asymmetrical hemline. She paired the loose-fitting frock with Christian Louboutin snake-print pumps.

The Vampire Diaries actress Kat Graham, 21, is known for her daring style so it was no surprise that she didn't play it safe on the red carpet. Her white feathered dress featured a sheer mesh neckline, structured shoulders and floor-length fringe. On a positive note, we loved her vibrant purple eye shadow and blue manicure.
