How to put it together

1
Put on the base clothing, starting with comfortable pants and a simple t-shirt.
2
Layer the firefighter jacket over the t-shirt and fasten the front hook-and-loop closures or buckles.
3
Tuck the pants into sturdy black rain boots to mimic real turnout gear.
4
Place the fire chief helmet securely on the child's head, adjusting the inner band if needed.
5
Equip the child with lightweight props like a toy fire extinguisher, a plastic axe, or a badge.

Makeup & hair

Keep hair simple and tucked neatly under the helmet. No makeup is required, though a tiny smudge of black face paint on the cheek can create a playful, post-rescue 'soot' effect.

Tips

Opt for lightweight plastic props so they are easy and safe for a child to carry while trick-or-treating.
Ensure the boots are well-broken-in and comfortable for walking long distances.
The reflective tape on the jacket adds excellent visibility for safety during dark Halloween night walks.
