Wear t-shirts from your favorite horror movies and match them with skater skirts. It can still be brutally humid in September and October. Pants might be too much, especially if you plan on getting there before the sun goes down. I prefer skirts (with pockets if possible), leggings or tights, and comfortable shoes.

For Halloween Horror Nights (HHN) in 2026, the best attire is a balance of comfort and compliance with Universal's strict safety rules. Most attendees wear horror-themed t-shirts paired with comfortable, breathable pants or shorts and, most importantly, sturdy walking shoes, as you will likely walk several miles. Universal's policy generally prohibits guests over 12 from wearing costumes or masks to prevent confusion with scare-actors, though themed apparel is encouraged. You should also bring a light layer, like a flannel or hoodie, as outdoor temperatures can drop during the night. Avoid any clothing that Universal deems "indecent" or "gruesome," and remember that face painting is permitted only if it covers less than half the face to allow for age/ID verification.
