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 events like Universal's Halloween Horror Nights, the unofficial "uniform" is comfortable, practical, and horror-themed. Because the event involves hours of walking and standing in long queues, sensible footwear (like broken-in sneakers) is the most critical item. Many fans wear horror movie t-shirts, flannel shirts, or "Spirit Jerseys" to celebrate the season. It is important to note that Universal strictly prohibits costumes and masks for adult guests to ensure they aren't confused with the professional "Scareactors" inside the haunted houses. Since the event takes place on select nights in September and October, the weather in Orlando or Hollywood can be humid but chilly at night, so "light layers" are recommended. Avoid wearing expensive jewelry or loose items that could be lost during a "jump scare" in a dark fog-filled scare zone.
