How to put it together
- 1
Put on your solid neutral base layer, including the long-sleeve shirt and matching pants.
- 2
Unpack the foam peanut tunic and let it sit flat for a few hours to remove any shipping creases.
- 3
Slip the peanut tunic over your head, aligning your arms through the side armholes.
- 4
Adjust the tunic so it sits comfortably on your shoulders and hangs straight down.
- 5
If going for the mascot look, put on the white gloves, place the monocle over one eye, and hold the cane.
- 6
Finish the look with comfortable dark sneakers or dress shoes.
Makeup & hair
Keep your hair simple or tucked away under the tunic hood. If your face is visible, no makeup is needed, but you can paint a small peanut shape on your cheek for a festive touch.

Tips
- If the foam tunic is wrinkled, use a garment steamer on a low setting on the inside of the fabric to smooth it out.
- Wear breathable cotton layers underneath, as foam tunics can trap body heat during indoor parties.
- Keep your hands free by opting out of the cane prop if you plan on holding drinks or snacks at a party.
Peanut costume FAQ
- How do I make a DIY baby peanut costume?
- Dress your baby in a tan sleeper or sleep sack, then use a brown fabric marker to gently draw a cross-hatch pattern on the front to resemble a peanut shell.
- Is the peanut costume comfortable to sit down in?
- Yes, foam tunics are flexible, but you may need to pull the bottom of the tunic up slightly when sitting to prevent it from bunching up.
- How do I turn this into a Mr. Peanut costume?
- Simply add a black top hat, a single-eye monocle on a string, white formal gloves, and a black walking cane to the standard peanut tunic.
Did you know? The peanut is actually not a true nut at all, but a legume that grows its seed pods underground, a unique botanical process called geocarpy.
