A plethora of celebrities were photographed attending Billie Eilish's Halloween party on Saturday, October 26. Kaia Gerber kept everyone guessing by covering up a potential Halloween costume with a stylish black blazer.
While a navy pleated skirt and the hint of a tie appeared to be peeking out from underneath, it was Gerber's sleek blazer that demanded attention. She paired the jacket with black riding boots, and carried a black Celine bag.
