Lupita Nyong’o As Dionne From ‘Clueless’
Probably the most iconic celebrity Halloween costume from the last few years is Lupita Nyong’o as Dionne Davenport from 1995’s “Clueless.” Lupita got dressed in a black and white skirt and blazer set, combined with a red cardigan and nose ring, and with a huge glittery cell phone straight out of the ’90s, Nyong’o perfectly copied the feisty character played by Stacey Dash. Lupita must be a perfectionist that she even wore green contact lenses and carried a tiny black bag.
