Kim Kardashian in a Black Halter with Kanye West | Pictures

Kim Kardashian showed some skin arriving at dinner with boyfriend Kanye West in Miami last night. The couple coordinated in matching shades of black and gray, while Kim stole most of the attention in a sexy cutout top. Kim's currently in the Sunshine State shooting Kourtney & Kim Take Miami, and during her free time, she's been hanging out with friends and searching for the perfect Halloween costume.

Kim caused a stir on Friday when she tweeted a photo of herself wearing a revealing costume. We've seen her dress up like Little Red Riding Hood, Wonder Woman, Poison Ivy, a pirate, and Snow White, but we'll have to wait and see if Kim picks another sexy Halloween costume or if she and Kanye surprise us with a couple's ensemble. Kim's just one of the celebrities excited for Halloween, and she's also approaching her birthday. Kim turns 32 on Oct. 21, and Kanye has his work cut out for him if he's going to top his last gift, a white Persian kitten named Mercy.
