The elegant affair was held at the Hemmesphere Bar on George St in Sydney, with both sisters happily mingling with Choo and his fellow party attendees.
Earlier in the day, the reality show siblings treated themselves to lunch at Otto's before heading off on a midday harbor cruise.
Kim, who wore a tunic top and jeans, and Khloe, sporting a jumpsuit, disembarked their ship at the fashionable Finger Wharf in Woolloomooloo, feeling relaxed and ready for another dose of fashion!
Enjoy the pictures of Kim and Khloe at the Jimmy Choo shindig and out on a Sydney Harbour cruise (April 30).
