💡 Tips for Choosing the Perfect Costume

Comfort first: Look for soft, stretchy jumpsuits rather than heavy layers.
Safety check: Avoid masks that block vision or long capes near open flames.
Layer up: A thin jumper or leggings underneath keeps little monsters warm during chilly nights.
Let them pick: Kids are more likely to wear and love a costume they’ve chosen themselves!
