Kim Kardashian is still living it up in Punta Mita, Mexico in the name of Kourtney’s birthday, and the girls are definitely not slacking on their style. While Kourtney is on the crusade to start a new bathing suit trend, Kim borrowed something from her younger sister.

Girls Trip

A post shared by Kim Kardashian West (@kimkardashian) on

North and Saint’s mommy shared a group photo where she posed next to Kourt in a body-hugging, olive green slip dress. She captioned the photo “girls trip.”

The dress is the Olive Short Cami Dress ($545) by designer Nili Lotan, and its made with 100 percent silk. Basically, it’s perfect for a hot vacation night, so no surprise Kim opted for it.

You might have noticed that Kim’s dress appears to be the same one that Kylie Jenner wore while out and about in Los Angeles last August. Kim opted not to accessorize the dress with anything, but Kylie went all out. She paired the slip dress with pointy ankle boots and a metallic belt with dangling chains.

Hey, it’s no secret the Kardashian-Jenners borrow from each other’s closets all the time, but it sure is nice to see big sis take a little sartorial inspiration from her youngest sister.
