Kourtney Kardashian Works Post-Baby Body in Khloe’s Animal-Print Dress: Who Wore It Best?

It’s a Kardashian throwback!

Kourtney Kardashian hosted the Marquee Dayclub’s season preview at The Cosmopolitan hotel in Las Vegas on Saturday, March 21. Her style of choice: an animal-print Roberto Cavalli maxi dress, which just so happened to be worn by her sister, Khloe Kardashian, in 2011!

When Khloe, 30, wore the dress to the 2011 Teen Choice Awards, she cinched it at the waist with a wide belt and added nude platform heels. She also went bold with her beauty choices with a Barbie pink lip and big, bouncy bombshell curls.

Three and a half years later, Kourtney, 35, who just gave birth to her third child, Reign, in December, worked the same style, seemingly plucked right out of her younger sister’s closet (as it hung a little long on her petite frame). However, she opted to use the easy, breezy piece as a cover-up instead, teaming it with minimal makeup and straight hair.
