2010 American Music Awards: The Three Top Trends

All you had to do to figure out what's hot in fall fashion was watch the 2010 American Music Awards, which aired last night. From feminine fabrics to new strand styles, the award show's red carpet was bustling with celebs decked out in the season's freshest fall trends. Here are our faves...

LACY NUMBERS

While they chose very different lengths, Kelly Osbourne, Christina Milian and Heidi Klum each went with lace looks for the red carpet. Kelly's little black dress was a nice contrast to her big, blonde bouffant 'do. Meanwhile, the lacy overlay made Christina's minidress even sexier, and Heidi's long lace gown with red piping at the waist was perfectly see-through and elegant.

HAIR MAKEOVERS

Celebrities know — if you want to make a quick and simple style statement, just switch up your hair. Taylor Swift traded in her usual wavy, flirty style for a sleeker, longer look with bangs. Ke$ha loaded her locks with hair spray for a gravity-defying mohawk, and Rihanna (whose red hot hair was to the middle of her back just a couple of days ago) went with a cute shoulder-length, Shirley Temple-style.

TRAILING TRAINS

These stars prove that you don't have to be getting hitched to wear a train. Miley Cyrus wore a white and pink shimmery wrap dress with a long thin train that you either loved or hated. Jada Pinkett Smith looked statuesque in gold, tiered dress with a train flowing behind her. Meanwhile, Rihanna seemed to blend right into the red carpet in her hair-matching, trained dress.
