Hot mama! Kourtney Kardashian wows in summer swimwear

Italy just got a lot hotter this summer!

Kourtney Kardashian was hanging out on a yacht off the coast of Italy earlier this summer with her three kiddos and her mom, Kris Jenner, and she made sure that her swimwear game was on point!

The 37-year-old reality star put on a wow-worthy show of one-piece swimsuits from the beach to the lido deck. She kicked things off this week in a sexy, black monokini which was simple and sophisticated. Then she stepped things up a notch with a bright gold one-shoulder one-piece, which she teamed with a set of matching gold shorts and shades.

Next up, she gave a shout out to her sister, Khloe Kardashian in a black suit that had write lettering across the front that read, "Khloe $$$."

Kourtney also rocked a nude two-piece in a fun selfie and she captioned the look, "yacht selfie."

Lastly, she polished off her fashionable swimwear with a navy suit with nude panels in a geometric pattern. It was perhaps our favorite look all week with subtle yet super sexy detailing.
