Kim & Khloe's Vegas Party Looks

The day before her Beiber party look, Kim Kardashian was out for Khloe's birthday in Las Vegas on June 17 - an early celebration for Khlo, whose birthday is actually on June 27.

While their guys kept it simple in shirts and jeans, Kim wore an Herve Leger dress with Christian Louboutin platforms and a YSL clutch.

And Khloe was in an embellished mini dress with the Louboutin "Maggie" pumps.
