You go together like peanut butter and jelly, so show how devoted you are with a cute couple's costume like our Unisex Peanut Butter & Jelly Adult Costumes. It comes with two suits, a one piece pull over designed to look like a slice of white bread with peanut butter, and another designed to look like a slice with jelly. Wear a black bodysuit or black pants, shirt, and shoes underneath to let this costume stand out, and make sure you take plenty of photos. This creative outfit is also great for best friends. No matter how old you are, everyone enjoys the occasional peanut butter and jelly sandwich. This lunch box classic is simple and delicious, and just wouldn't be complete without the other component, just like you and your significant other.
