Thanks to many rowdy bashes this week — Halloween-related or otherwise — looks from the party circuit were killer. Lupita Nyong’o dressed as a picture-perfect version of Dionne from the ’90s film Clueless and Sarah Hyland showed us how much she loves Taco Bell. On the non-costume side, Priyanka Chopra wore an elegant silver gown to a rooftop party in New York, and Eva Chen wore a sequined number with shimmering heels to match to a party at Saks Fifth Avenue celebrating the launch of her children’s book. Who wore the best look? Scroll to see everyone below.
