The sisters are enjoying fun in the sun in an array of stylish swimwear while in Turks and Caicos

The Kardashian-Jenner sisters have their PhDs in 𝑠e𝑥y vacation style.

Kim Kardashian, 43, is enjoying a beach getaway with her sisters Khloé, 39, Kourtney, 44, and Kylie Jenner, 26, in Turks and Caicos, so of course, there’s no shortage of 𝑠e𝑥y beach photos. All four have been sharing photos from their time in paradise, which has included lounging on the sand and swimming in crystal-blue waters.

The entrepreneurial family has also taken the opportunity to show off their swim style on Instagram. Featuring suits from Kim’s clothing brand Skims, the sisters are serving up some serious summer beach inspo, with everything from one-piece suits to revealing bikinis.

Kim donned a brown snake print bikini which she accessorized with layered necklaces and a cowboy hat.

“This ain’t Texas… it’s Turks,” she captioned an Instagram carousel showing off her look (and referencing Beyoncé’s song “Texas Hold ‘Em” from her new album Cowboy Carter).

In one photo, Kim and Khloe lounge on the beach, twinning in snake print ensembles. While Kim is in a bikini, Khloe rocks a chic one-piece and matching head scarf.

On her own Instagram, Khloe enjoyed the ocean water in a gold one-piece swimsuit and fishnet cover-up, tagging her sister Kim’s brand Skims in the photos.

In a simple black bikini, Kourtney hilariously recreated Kim’s infamous lost-earring incident from season 6 of their show Keeping Up with the Kardashians.

“My diamond earring came off in the ocean and it’s gone,” she captioned a set of photos of her splashing around in the water and reaching for her ears.

Kourtney, who welcomed son Rocky Thirteen with husband Travis Barker five months ago, went on to share a heartfelt message to fellow new moms.

“Your body is beautiful at all stages. During pregnancy as we are glowing and growing, postpartum as we are healing and shrinking, and then that period I find the hardest as our bodies are still adjusting,” she wrote on Instagram Stories along with a photo of herself in a bikini.

“And if you’re breastfeeding, that’s a whole other part of it. I try to be kind to myself as my body finds a new normal. The pressure put on us to bounce back when everything is new and different isn’t realistic. Life is beautiful, you are beautiful. Just a little reminder (for me too;) XOXO.”

In addition to Rocky, Kourtney is mom to sons Mason, 14, and Reign, 9, as well as daughter Penelope, 11, whom she shares with ex Scott Disick.

Kourtney also took a moment to poke fun at herself during their sister vacation. The Poosh founder shared Kim’s photo of her and Khloe sprawled on the beach in which Kourtney appears in the distance in a lounge chair.

“I love taking pics with my sisters!” she jokingly captioned the post on Instagram Stories.

While Kylie hasn’t appeared in photos alongside her sisters, it seems she’s also enjoying a vacation in Turks and Caicos. The beauty mogul captioned a recent post, “back in paradise,” while posing in a studded black bikini by Chanel.
