Choose a base outfit: Use an old t-shirt, hoodie, or dress in a solid color that matches your costume theme (e.g., black for a cat, white for a ghost).

Create simple accessories: Cut felt into ear shapes and attach to a headband for animals like cats or bats. Use safety pins or hot glue (adult supervision required).

Make a mask: Use construction paper to cut out eye holes and decorate with markers, glitter, or stickers. Attach elastic string or a popsicle stick for holding.

Add face paint: Use washable face paint to draw whiskers, a spiderweb, or zombie details. Always do a patch test first to avoid skin irritation.

Decorate with crepe paper: Wrap orange or black streamers around arms or a hat to create a festive pumpkin or witch look.

Final touches: Add sunglasses for a robot or superhero vibe, or stuff socks into sleeves for a funny inflatable costume effect.
