Select a theme that accommodates the ages, sizes, and preferences of all participating siblings.

Add the defining character elements, such as matching hats, vests, capes, or custom printed shirts.
4
Equip each sibling with their respective safe, lightweight props and coordinated trick-or-treat bags.
