Khloé, who recently turned 40, wore a white eyelet mini-dress and finished her look with a pair of sunglasses, white sneakers, and a delicate diamond pendant.

However, fans struggled to understand what the party’s dress code was after Khloé shared a video of Kim, 43, making her arrival in a floor-length gold gown.

“Wowie, the Golden Globe is here, ladies and gentlemen!’ Khloe teased her sister, as Kim was accompanied by her youngest daughter Chicago West, six.

“You are the party!” the Good American founder added.
