It's a style showdown between a sexy supermodel and reality show vixen!
Alessandra Ambrosio hit the red carpet at the 2014 Latin Grammy Awards on Thursday night, showing off some major cleavage -- and lots of leg -- in a black and white Balmain beaded mini with a cape topper.
The Victoria's Secret Angel completed her rocker-chic ensemble with classic black pumps, smokey eye makeup and a whole lot of sex appeal.
We first spotted this bold look on Kim Kardashian, who sported a similar, red and black version at the MTV VMAs earlier this year.
Mrs. West added some edge with woven Balmain sandals, Lorraine Schwartz jewels, a nude lip and her hair in loose waves.
We're going to give this one to Kim because of her fun accessories, but we want to hear from you!
