I'm sorry, I have to put this out there.  For a fifteen year old, Miley Cyrus looks like a w*ore.
Everyone looked terrible, IMO.  No personality, just a parade of bad, boring dresses.  Beyonce's hair didn't bother me so much as her Givenchy knock-off by Elie Saab.  I kind of liked the direction Nelly Furtado thought she was going in, but it really just wasn't right for her anatomy or established aesthetic.
I really hated Alicia Keys mohawk.
