Kim Kardashian Posts Selfie in Sister Kylie's Bikini

One of our favorite things about a Kardashian family vacation is all the outfits the sisters will share on Instagram. And Kim Kardashian makes it particularly easy to keep up with the Kardashian's due to her disciplined posting schedule. This time the krew is down in Miami, which means Kim is back in her bikini. Well, Kylie’s bikini to be exact.

The reality star posted a photo Wednesday showing off her curves — and toned post-baby body — in a tiny black Lolli bathing suit, the same suit Kylie Jenner wore earlier in the day for a tour of the Versace mansion. “Yep stole Kylie’s bikini…she’s not getting it back,” she captioned the below photo on Instagram.

Aside from swiping from her sister’s suitcase, Kim also introduced us to a new outfit style: crop tops over dresses.

It’s not exactly a #DiorDressICutInto2Pieces moment, but the look still has our attention. Kim sported a Kardashian Collection midriff-baring turtleneck over a vintage Azzedine Alaïa dress. We appreciate her mix of high-low style, but we’re not sure how we feel about this combo. (Seriously: turtleneck + Miami = sweat.) The reality star is definitely digging it though, showing it off in one of her patented skinny mirror selfies (below).

And though Khloé Kardashian has been poking fun of Kim on Keeping Up with the Kardashians for her extremely neutral-coloured wardrobe, she took a page out of her sister’s style playbook in a beige jumpsuit.
