How Fashion People Do Halloween Costumes

Halloween is fast approaching, and while most of us at STYLECASTER are avowed fans of the last-minute DIY costume, you can bet not everyone—least of all dress-up-happy fashion folks—is leaving theirs to the eleventh hour.

Thanks to Instagram, we know what our favorite models, designers, and street-style stars wore last year, which means you’re free to mine their feeds for inspiration (don’t worry, we won’t tell).

Wondering how Britney Spears‘ “Oops! I Did It Again” catsuit would look like IRL? Let Camille Rowe be your spirit guide. Considering attempting Marilyn Manson makeup at home? Check out Eva Chen‘s brilliantly creepy costume from 2015.

In the gallery, see what Victoria’s Secret models, Vogue editors, and Derek Blasberg‘s very stylish posse wore last October 31.
