Kendall Jenner’s got legs for days and she’s not afraid to flaunt ‘em!

On Monday, March 12, the reality star joined many of Hollywood’s famous faces at the LA premiere of The Hunger Games. Keeping all eyes on those mile-long stems, Kendall opted for a turtleneck mini by Azzedine Alaia paired with edgy yet flirty Miu Miu bow heels.

Subtle bronze makeup and a super sleek pony were sophisticated touches that didn’t compete with the dress.

But the minute Kendall stepped in front of the crowd, we knew we’d seen that dress on a Kardashian before. Back in 2010, her big sis Kim donned the same Alaia frock while attending a party for E!’s reality show The Spin Crowd.

Kim kept herself warm in opaque black tights and Prada peep-toe heels, topping off the look with an Alaia studded belt for a bit of punk appeal.

Looks like Kendall’s exercising her right to go swimming in her sister’s closet. (Hey, if we were related to Kim, we’d do the exact same thing!) The question is, who worked this Alaia dress best?
