Though an odd couple to say the least, Gru and his mad scientist buddy Dr. Nefario make a cool couples costume idea for fans of the 2010 film Despicable Me. With a sequel coming out this year in 2013, it’s also a great excuse to bring back your favorite characters from the movie. Gru’s costume is very plain and simple and consists mostly of gray and black. Pair a gray sweater with black slacks and wear a gray and black stripe scarf. Dr. Nefario just requires some crazy white hair, goggles, a yellow shirt, a white lab coat, and rubber gloves. Stand side by side and your Despicable Me costumes will really come alive.
