How do you make a DIY cake costume?

You can construct a cake slice shape using two large cardboard triangles connected by side panels. Paint the sides white or pink for frosting, add colorful felt sprinkles, and attach shoulder straps to wear it.

What should I wear under a cake costume?

Wear a solid, neutral base layer like a white or pastel pink long-sleeve shirt and leggings so your clothing doesn't distract from the cake design.

Is a cake costume comfortable to wear?

Yes, especially if made from lightweight foam or fabric tunics. Cardboard versions can be bulky, so ensure you have plenty of legroom to walk comfortably.

How to put it together

1
Put on the solid-colored base layer shirt and pants to keep the focus on the cake structure.
2
Slip the wearable cake tunic or cardboard cake slice harness over your shoulders.
3
Adjust the shoulder straps so the cake sits comfortably at waist level.
4
Secure any loose sprinkles or decorative frosting trim using fabric glue or safety pins.
5
Place the candle headband securely on your head, ensuring the flame stands upright.
6
Finish the look with comfortable white sneakers or pastel-colored shoes.

Makeup & hair

Keep hair simple with a high ponytail or bun to keep it away from the candle headband. For makeup, apply bright pink blush, a touch of face glitter, and a sweet pastel pink lipstick to match the frosting theme.

Tips

If making a cardboard cake, ensure the armholes and neck opening are cut wide enough for easy movement.
Keep the costume lightweight by using craft foam instead of heavy cardboard for the main structure.
Wear comfortable shoes, as the bulky shape of a cake costume makes navigating stairs a bit tricky.
Add battery-operated fairy lights to the candle flame for a glowing effect at night.
