It's the official costume guidelines - they reserve the right to refuse you admission if you don't follow them....
"Costume Information
All event attendees including adults may dress in their favorite Halloween costume and must follow these and other guidelines as determined solely by Disney:
Costumes should be child-friendly and may not be obstructive, offensive or violent.
Guests may wear masks. However, masks must not obstruct vision and eyes must be visible at all times.
Guests that dress like Disney Characters may not pose for pictures or sign autographs for other Guests.
Costumes should not drag on the ground.
Costumes should not contain sharp objects, pointed objects or materials that may accidentally strike another Guest.
Costumes should not contain any weapons which resemble or could easily be mistaken for an actual weapon.
Guests of all ages may only wear costumes to the Mickey's Halloween Treat event to which they have valid tickets. During normal Park operating hours, costumes are only permitted for Guests ages 9 and younger.
Guests that do not adhere to these guidelines may be refused entry into the event unless their costume can be modified to meet the above standards. "
Have fun!
