Disneyland has a reputation for kicking off Halloween season earlier than almost anywhere else, and Oogie Boogie Bash, the after hours party held at Disney California Adventure, is a huge part of that tradition.

The event is already underway and runs through October 31, bringing treat trails, seasonal entertainment, and even a character making its Disneyland park debut this year. One of the things that makes this particular party stand out from a normal day at Disneyland, though, is that it's actually a costume party, meaning guests get to dress up in ways they normally can't during regular park hours. That freedom comes with a fairly detailed rulebook attached, and knowing those rules ahead of time can save you from an awkward conversation with security at the gate. Here's a full breakdown of the 12 dress code rules currently in place.
Costumes Are Actually Allowed, With One Big Catch

Under normal circumstances, Disneyland doesn't allow guests to dress up as actual characters and walk around the park, which is exactly why Disneybounding, dressing in a way that subtly references a character through color and style rather than a literal costume, became such a popular workaround among fans. Oogie Boogie Bash pulls back on that restriction significantly. According to Disney, “All Guests may dress as their favorite character, but may not pose for pictures or sign autographs for other Guests.” In other words, you can absolutely show up as your favorite villain or hero for the night, just don't expect to be treated like an official character meet and greet if other guests come up wanting photos or signatures.
Costumes Still Need to Stay Family Friendly

Even with the added freedom, Disney is clear that there are limits on what kind of costume actually works for the event. The company states plainly that “costumes must be family-friendly and may not be obstructive, offensive, objectionable or violent.” That means anything overly graphic, gory, or generally inappropriate for a family audience isn't going to fly, no matter how impressive the craftsmanship behind it might be.
No Weapons, Sharp Objects, or Anything That Could Hurt Someone
Safety is clearly a top priority in how these rules were written. Disney specifies that “costumes may not contain any weapons that resemble or could easily be mistaken for an actual weapon. Costumes may not contain sharp objects, pointed objects or materials that may accidentally strike another Guest.” This rule makes sense given how crowded the party gets throughout the night, since even a costume prop that seems harmless in a mirror at home could easily become a hazard once you're moving through packed walkways with thousands of other guests.
Disney also notes that layered costumes or props that wrap around the entire body may be subject to additional security screening. If your costume involves a lot of bulk or hidden compartments, expect security to take a closer look before you head inside.
Dresses and Robes Can't Touch the Ground
Practicality plays a role in these guidelines too. Disney states that “costumes may not reach or drag on the ground,” specifically calling out the example of full length princess dresses. While that might disappoint anyone hoping to go all out with a floor length gown, it makes sense from a safety standpoint, since a dragging hemline becomes a tripping hazard fast in a crowded event environment with people moving in every direction.
Kids 13 and Under Get a Little More Flexibility
Younger guests catch a bit of a break when it comes to masks specifically. Guests ages 13 and under are allowed to wear certain masks as long as they don't cover the entire face, and the eyes must remain visible at all times. It's a reasonable middle ground that still lets younger trick-or-treaters feel like they're in full costume without completely obscuring their identity in a crowded park setting.
Guests 14 and Older Have More Specific Guidelines
Once guests hit 14 and up, the rules get a bit more detailed. Capes are allowed, but only if the length doesn't reach or drag on the ground, mirroring the same logic applied to full length dresses. Themed T-shirts, blouses, sweatshirts, and hats are all completely fine, and several costume accessories are specifically called out as acceptable, including transparent wings, plastic lightsabers, toy swords, and tutus. Headwear is also permitted, as long as it doesn't cover the face.
Masks Are a Hard No for Most Guests
While younger children get some leeway on partial masks, the rules are much stricter for everyone else. Unless a mask is being worn for a documented medical purpose, “masks of any kind may not be worn” by guests overall. This is likely tied directly to security and identification concerns in a large, crowded event, since fully obscured faces make it much harder for cast members and security personnel to monitor the crowd effectively.
Disney Takes These Rules Seriously
This isn't a casual suggestion list either. Disney explicitly states that anyone who doesn't follow these guidelines “may be refused entry into, and/or removed from, the event” unless they're willing to modify their costume to meet the requirements. That's a real consequence worth planning around, especially if you've spent serious time and money building an elaborate costume specifically for the occasion. Showing up with a costume that violates one of these rules could mean scrambling for a last minute fix or being turned away entirely.
Getting the Most Out of Your Costume While Staying Within the Rules
Disney genuinely wants Oogie Boogie Bash to be a showcase for creativity, and there's clearly room to have real fun with a costume as long as it stays within these guidelines. Sticking to accessories like plastic weapons instead of anything metal or sharp looking, keeping hemlines above the ground, and skipping full face masks unless medically necessary will keep you well within the rules while still letting you show up as whichever character you're most excited about.
It's also worth remembering that these rules are subject to change without notice, so it's smart to double check Disney's official Oogie Boogie Bash website close to your visit date rather than relying purely on information from earlier in the season. A quick check before you finalize your costume could save you a frustrating moment at the gate.
