Marla Singer, played by Helena Bonham Carter in “Fight Club,” may not be glamorous, but her clothes represent her character: chaotic, mysterious, and a little damaged. With a messy bun, fake cigarette, and smudged eye makeup, you’re well on your way to imitating her iconic character. An all-black outfit, preferably with a faux fur coat of some kind, completes the look. this costume is fairly effortless, because if you look a little messy or unkempt, it only serves to enhance the costume and really channel your inner Marla.
