While Khloe opted for a pair of figure-flattering high-waisted trousers with a pair of leg-lengthening nude pointed courts, Kim went all out in the body con dress.
Kim, who's worked hard to get her pre-pregnancy figure back before her wedding to Kanye later this year, flaunted her toned thighs in the hip-hugging style.
And the reality star emphasised her slim legs in her favourite Azzedine Alaia nude circle detail sandals, showcasing her immaculate pedicure.
But Kim kept her cleavage under wraps in a long sleeved, high necked top, which helped accentuate her slim waist.
Kim, 33, wore her hair pulled back into a sleek, chic ponytail, and finished off her look with a gorgeous embellished clutch bag with an oversize gem-encrusted clasp.
The sisters were in town for the launch of the latest Kardashian boutique, on Miami Beach.
