Imaginary Boyfriend Costume (Disney / Pixar's Inside Out)
Imaginary Boyfriend is a minor character from Disney’s Inside Out. He loves to say “I would DIE for Riley!”
Dark Green Plaid Button-up Long Sleeve Shirt
It sometimes looks like he’s wearing a black jacket but he’s actually wearing a dark green plaid button-up long sleeve shirt. A black jacket works well too as it’s more common.
Speech Bubble Sign
Since the costume is fairly simple and looks like every day clothes, you need something to set you apart. Imaginary boyfriend’s favorite line is “I would die for Riley.” Make a large speech bubble sign that says “I would die for Riley” and put it on a stick so that you can carry it around.
