How to put it together

1
Put on your neutral base layer of clothing, such as a white long-sleeve shirt and white pants to act as the inner marshmallow.
2
Prepare the graham cracker boards by drawing a grid of dots and a dashed center line on two square pieces of cardboard.
3
Cut a piece of dark brown felt slightly wider than the cardboard to serve as the melting chocolate layer, letting it drape over the front board.
4
Attach the front and back cardboard panels together using two strips of wide ribbon glued or taped to the top inner edges, creating a sandwich board that rests on your shoulders.
5
Slip the sandwich board over your head so one cracker rests on your chest and the other on your back.
6
Adjust the height so you can walk and sit comfortably.

Makeup & hair

Keep makeup simple with warm, toasted bronzer on the cheeks. Hair can be styled naturally or tucked into a white beanie to resemble the top of a marshmallow.

S'mores for couples, groups, kids & more

couples: One person dresses as a toasted marshmallow, and the other wears a combined chocolate and graham cracker sandwich board.
group: A perfect trio costume where Person 1 is a Graham Cracker, Person 2 is a Hershey's Chocolate Bar, and Person 3 is a Jet-Puffed Marshmallow.
kids: A soft, plush wearable cube tunic shaped like a marshmallow with printed cracker details on the front and back.
Plus size: Use extra-wide cardboard panels or flexible foam sheets for the crackers to ensure a comfortable, roomy fit over the torso.
pet: A small dog harness attached to two light brown felt squares on the sides with a white plush fabric wrap around the middle.

Tips

Make sure the cardboard panels do not extend past your knees so you can easily climb stairs and sit down.
If wearing this outdoors in cool weather, the sandwich board easily fits over a thick winter coat.
Use lightweight foam board instead of heavy shipping boxes to keep the costume comfortable for long hours of wear.
