The Sexiest Summer Bikini Bodies of 2015

As summer winds to a close, celebrities are squeezing in their final beach days of the season!
Before they hang up their bikinis until next year, we're taking a look back at some of our favorite bathing suit moments of the summer.
Beyonce and Blue Ivy

The matching snakeskin bathing suits are one of the cutest things we've seen this mother-daughter duo pull off, and that's saying a lot. Oh... and happy birthday, Beyonce! The pop diva turned 34 on Friday.
Katy Perry
The "Roar" singer gave a sassy pose on the back of her new "whip," wearing a purple two-piece decked out with seagulls.
Taylor Swift
The singer and her squad sent fans greetings from Maui.
Jennifer Lawrence and Amy Schumer
The new besties built the most beautiful human pyramid on a boat with friends somewhere off the coast of New York.
Bella Hadid
Gigi Hadid's little sister, also a model, flaunted her backside in a black thong.
Jessica Simpson
It's clear the singer's two children haven't taken anything away from her figure, as she left little to the imagination in this risqué cutout.
Kendall Jenner
Great minds think alike! Kendall rocked the same Dakota cutout for an Allure photoshoot.
Demi Lovato

The "Cool for the Summer" singer stayed just that in a barely-there black bikini while debuting her single.
