Katy Perry went the quirky route that year and dressed as a Cheeto. Underneath her snack-inspired costume, she donned a red bodysuit and matching sneakers.
For her Halloween party in 2015, Heidi Klum transformed into Jessica Rabbit. She wore a strapless red gown with a daring slit, prosthetics on her chest and face, purple latex gloves, and red pumps.
At the same party, Emily Ratajkowski dressed as Marge Simpson. But rather than wearing yellow clothes underneath her green minidress, she painted her entire body from head to toe.
