For celebrities, choosing the perfect Halloween costume can be taxing, because everyone wants to stand out. As seen from last year’s turnout — from Beyonce’s electrifying Storm ensemble to Heidi Klum’s jaw-dropping Jessica Rabbit transformation — the competition in Hollywood is stiff.

From outfits that were culturally offensive, needlessly naughty or basic beyond repair, check out our gallery above to see how stars like Colton Haynes, Julianne Hough and Chris Brown made our list for their tacky costume choices.
