If there is one true character from the Simpson that you associate with alcoholism it’s Barney, the overweight friend who is always in Moe’s bar. And the next guy you associate with beer is Duffman. Put the two together and you have a match-made-in-Heaven of a Simpsons couples costume. Barney’s costume is really fun if you are willing to bare your midriff. You can do this easily by buying a red shirt that is a few sizes too small to fit on you. Barney’s costume isn’t complex at all, so you can just wear some blue pants or jeans. Duffman’s costume is much more extravagant and is really just a blue and red superhero ensemble. Duffman has a blue sleeveless shirt and blue paints paired with a red cape and cap with the word Duff on it. Since he’s such a popular character from the Simpson, you can just buy his costume outright, thankfully.
