Kim Kardashian In Miami Beach

Kim Kardashian is soaking up as much sun as possible during her stay in Miami Beach.

Kim was joined by Kourtney, Kanye and Larsa Pippen Saturday on a shopping trip ... we're guessing they're all in town for nightclub exec Dave Grutman's wedding. 

One thing's for sure ... she'll want to stock up on some Costco-sized SPF.
