In a year that will bring smaller, socially distant Halloween celebrations, ditch the single-use costumes for ones that make use of the jeans already in your closet—or on your shopping list.
Halloween offers the perfect excuse to try on flare jeans or test your sartorial boundaries with Y2K denim style.
The best—and most sustainable—kind of Halloween costumes are the ones that you can wear after Oct. 31.
Tiger King

Among the strange turns of events in 2020, the Netflix documentary “Tiger King” united viewers during the start of quarantine. Now fans can channel the same energy of the film’s star Joe Exotic with a big cat-themed costume that will get everyone talking. Pair a bold top with light-wash jeans and purple aviators.
