Last updated: September 2026 In need of an easy and last-minute Halloween costume idea? Wednesday Addams has you covered! The best Halloween costumes, especially for adults, are the ones you can pull together from pieces already in your closet. This look comes together with five simple staples, most of which you probably already own — and the payoff is a costume that's both easy and unmistakably Wednesday. 5 Staples for an Easy Wednesday Addams Costume Plain Black Dress A simple 3/4-length or long-sleeve plain black dress is the perfect canvas for this costume. Either a fitted dress or an empire-waist dress works. Just make sure the neckline is high enough that a shirt collar can peek through underneath. White Button-Down Next, a white long-sleeve blouse. It should be long enough that you can pull the cuffs out and fold them over your dress sleeves. If your blouse runs shorter than your dress, roll up the dress sleeves slightly so there's enough blouse to fold over. Scalloped Over-the-Knee Tights Wednesday Addams reads as a young girl — which is exactly why scalloped over-the-knee tights make the look. Paired with pigtails, they're what sells the whole costume as authentic. For extra credit, add a small teddy bear. Mary Janes or Oxfords A Mary Jane or Oxford heel completes the costume — and keeps your feet comfortable for a full night out. A rare costume that doesn't sacrifice comfort for accuracy. Braids Wednesday is known for her long, dark pigtails, parted straight down the center. Easy enough with long hair; if yours is shorter, extensions or a dark wig from any Halloween supply store will get you there. Don't forget to rock a frown — Wednesday is serious, and more than a little creepy, and the deadpan expression sells the costume as much as the outfit does. Happy Halloween! Hope this helps you make an easy last-minute Halloween costume. Happy Halloween! Xo, Sarah Shop This Look Get the tights that make this costume work: Shop Scalloped Over-the-Knee Tights
