VIDEO : Khloé Kardashian & Kim Kardashian Share Clothing Again--Which Sister Wore the Sexy White Dre

It's a Kardashian sister showdown...again! Kim Kardashian and Khloé Kardashian have had many matchy-matchy moments in the past (more on those later), and their latest sartorial sister act caught our attention for being, well, white-hot. Khloé stepped out to the Opening Ceremony and Calvin Klein launch party with little sisters Kendall Jenner and Kylie Jenner wearing a plunging white Wes Gordon design that looked fairly familiar. That's because Kim donned the slit-to-there get-up almost a year ago while heading out on the town with mom Kris Jenner.??
