This is one sexy fashion face-off!
Kylie Jenner took to Instagram to show off her insane cleavage in a sexy Agent Provocateur swimsuit, which she snagged from Kendall Jenner's closet.
You might recognize the black cut-out one-piece from the 19-year-old's March pictorial in Allure magazine, which was shot by famed photographer Mario Testino.
Kylie added her own spin to the swimsuit, pairing the look with gold pendant necklace and baby-blue hair extensions for her new line.
But Kendall couldn't let Kylie have all the fun!
The seasoned supermodel also shared a poolside picture of herself over the weekend. She showed off her killer curves in a tiny orange bikini, which she accessorized with a long necklace and mirrored aviator shades.
Kourtney Kardashian also slipped into some beachwear while playing with her kids, Mason and Penelope.
