Kourtney opted for a more relaxed look, but took a note from Kim, showing off her toned legs in a pair of leather shorts and a black tank top, which she paired with a long white, sheer jacket and strappy heels.
Kourtney even commented on her sisters’ show-stopping looks in a hilarious Snapchat.
"What the f**k are we doing, Khloe? I have three kids waiting and you guys are getting ready for the f**king Oscars," she jokingly yelled at Khloe.
And not to be left out, Blac Chyna got the mini dress memo, arriving to the soiree in a white long-sleeved dress that hugged every curve -- including her growing baby bump!
