Steamy sisters! Khloe Kardashian and sister Kim rocked ultra-sexy looks while shopping with the rest of their family in St. Barts on Monday, Aug. 17.  

The matching style showed off Khloe's hot "revenge body" and Kim's baby bump, but Khloe's getup takes the cake when it comes to sex appeal.

The blonde-haired star, 31, looked phenomenal in her slinky black number, flashing major side boob, toned arms, and long legs (courtesy of a thigh-high slit). Khloe accessorized the all-black look with white and gold bracelets, her signature hoop earrings, aviator shades, and black Chanel "Diamante" jelly sandals.

All her recent photo shoots and street style pics have been illustrating Khloe's pride for the body she worked so hard to get. "Yeah, it's a revenge body," James Harden's girlfriend told Women's Health in the September issue. "But it's just as much for all my critics who called me 'the fat one' for my entire existence."

Kim, 34, who is pregnant with her second child with husband Kanye West, wore a similar style, opting for less side boob action and instead emphasizing her bump. The Selfish author looked radiant, pairing the style with matching gold bangles on either wrist, and played up her makeup—a sultry red lip and smoky eye—while slicking her long black hair into a low chignon.

The whole family is busy filming a vacation episode of Keeping Up With the Kardashians on their luxe island getaway, and spent the day shopping, playing around on ATVs, and taking in the sun.
