Some BIG stars are expected to hit the red carpet tonight in Las Vegas for the 47th Annual Academy of Country Music Awards -- and over the years, they've had some hit or miss fashion.
Taylor Swift is always a fan favorite at the annual ACM event, and since she first hit the scene back in 2006 she had a totally different style than she has now. While she wore cowboy boots and a patterned, girl-next-door dress to her first show, she's slowly transformed into a goddess-gown kinda gal with a more glam look.
Nicole Kidman has always been hit or miss with her looks ... but one accessory always remains on the hot list: Her husband Keith Urban!
Other fashionistas include Carrie Underwood, Kellie Pickler, Julianne Hough and Martina McBride -- check out all their red carpet looks from the past five years above!
And be sure to check back later tonight when all the stars hit the red carpet again. We'll be bringing you all the hottest looks as they come in!
