Kendall & Kylie Jenner's St. Bart Bikinis Are Awesome, Plus 9 Other Times They Gave Us Swim Style Inspo This Summer

The Kardashian-Jenner clan is soaking up the last bit of summer sun this week, vacationing on the island of St Bart's. Kendall and Kylie Jenner posted a bikini selfie to Instagram Tuesday before heading out on a boating adventure with the fam. No doubt these young ladies are ending their summer style on a positive note.

After celebrating her 18th birthday at Nice Guy in West Hollywood, followed by a mini vacay in Punta Mita, Mexico, I assumed the youngest Jenner would be all glammed out from the many wardrobe changes that ensued. But the Jenner sisters rarely disappoint when it comes to their water-friendly wardrobe, and their boating attire was no exception.

Snapping a standard hotel mirror selfie before throwing on their denim short-shorts (which they casually left unbuttoned btw), the sisters stunned in their designer swimwear. Kendall opted for a simple olive green bikini while Kylie wore a silver mesh two piece. "We woke up in paradise too," the selfie queen, otherwise known on Instagram as King Kylie, captioned the shot, which not only gave followers all the swim style inspo, but all the jealous feels. Back to school vibes are coming on strong these days, even for adults.

Since September is just around the corner, I'm encouraging you to take advantage of the last few weeks of the summer months. Slip into your favorite swimsuit, soak up some sun, and check out nine other times this summer Kendall and Kylie Jenner provided us with swimwear style inspo in 2015.
