At the American Music Awards, nothing is off limits on the red carpet. Thus, we're always treated to a range of gorgeous looks in every hue, length, and degree of textural intrigue. And last night, it was Taylor Swift, Carrie Underwood, Stacy Keibler, and Kerry Washington who got our votes for best dressed. Amped-up embellishments were big on the Fall '12 runways, so it was no surprise to see music's biggest stars reaching for dramatically jeweled dresses. Watch today's Fab Flash to get the rundown on all these looks now. On Allison McNamara: Greylin jacket, StyleMint top, House of Lavande bracelet.
