For the 2026 Halloween season, Disney's attire policy depends on whether you are attending a standard day at the park or a special ticketed event like "Mickey’s Not-So-Scary Halloween Party." For regular daytime visits, guests ages 14 and older are generally prohibited from wearing full costumes; instead, they are encouraged to use "Disneybounding," which involves wearing everyday clothes styled to evoke a specific character through colors and accessories. However, during the specific Halloween party nights, the rules are relaxed significantly. Adults can wear full costumes, but they must remain family-friendly and cannot be obstructive or offensive. You are not allowed to wear capes that drag on the ground, and full-face masks are strictly forbidden for adults (though children under 14 may wear them if eyes are visible). Additionally, you cannot pose for photos or sign autographs as if you are the actual character, as this confuses other guests. It is best to choose lightweight, breathable materials, as early autumn in Florida and California can still be very hot and humid for a long day of theme park walking.
