You'll definitely be the entertainment of the party alright, though it won't be your jokes that do it. The Adult Sweetheart Harlequin Costume is a way to join the high court of Halloween costumes this year. The outfit features a dress with a large cutout on the chest. The top of the dress is half black and white striped while the other half is pink, black, and gold in a diamond pattern. The skirt of the dress comes in a tutu style and matches the pink and yellow on the top. A pink ruffled choker matches the pink puffed shoulders of the dress and finishes the look. There's more harlequin accessories on our site to help enhance the costume. You'll be the most vibrant, and best looking, harlequin at the party when you show up in this.
