Kylie kicked it off yesterday by snapping and sharing this pic in a barely-there Agent Provacateur swimsuit.
It's not that the girls spent the entire weekend in bikinis -- they also threw on some skin-baring gowns to support their friend Cara Delevingne at a special screening of her new film, "Paper Towns." Kendall, 19, rocked a burgundy Zimmerman ensemble, throwing an Angelina-esque leg out there, while Kylie, 17, went with a sheer gown and bikini bottom paired with a suede jacket.

"Paper Towns," based on the novel by John Green, is out July 24th. The Jenner sisters will be out whenever and wherever there are cameras.
