Fourth of July is right around the corner, and usually that means pool parties, and pool parties mean wearing a swimsuit. Well Kourtney Kardashian and Khloé Kardashian Odom offer up their know how and knowledge and give tips on finding the right style to show off—or conceal—what ya got. The E! reality stars of Keeping Up With The Kardashians offered up some useful tips on what to do with the pesky swimsuit.

BIKINIS: They’re not just for skinny girls. "Diane von Furstenberg has a very mod, 1950s bikini where the bottom is kind of high-waisted—very Marilyn Monroe and very sexy," Khloé says. "So if you have a little tummy, you can hide it. BREAST IN SHOW: Make sure your bikini top has the proper support. "My boobs are enormous so I need extra support," reveals new mom Kourtney. "Knowing if you do or don’t need that extra support is important." Khloé adds, "I’ve seen women on the beach and I don’t know if they don’t see it but their breasts are hanging all the way down. They need some more support."

KNOW YOURSELF: The most important thing above all else is to know your body. "You have to know what suits your body best," Kourtney says. And Khloé warns, "Don’t just buy what everyone else is buying." Hopefully Kourtney and Khloe Kardashian’s insight can help you choose the bikini that is right for you.
