Summer is definitely Kourtney Kardashian's season, in addition to a slew of other stars.
The mother of three has all but lived in swimsuits over the past few months, and while she's arguably the MVP of bikinis, Kourtney is not the only celebrity to put on a stylish, sexy display during vacation.

6. Ashley Graham
The 29-year-old supermodel has made a career out of showing off her curves in stylish, sexy swimsuits.
Graham recently spoke with ET about the trials she faced regarding her size when coming up in the modeling industry. "Everything was about exterior, everything was about weight for me," she recalled. "I really had to step back and say, 'OK, am I looking for love through sex? Am I looking for love through food? Am I looking for love through the affirmation of fashion people who don't understand my body?' I had to really have, like, a come to Jesus moment."
