If someone you know resonates with Harlequin's jovial spirit, our modern take on the diamond-clad character's outfit makes a fun costume for kids. This costume is very easy to make and requires little work on your part beyond basic sewing. To start, you'll need an ordinary white button-down shirt, white tights, white ballet shoes, and dance shorts for under the costume. The most important part of the costume—multi-colored diamonds—is achieved by ironing on satin shapes in varying sizes. The diamonds should be applied to the shirt and hand-sewn bustle. Of course, no Harlequin costume would be complete without face paint. While you can take some liberties with this part of the outfit, we've provided a template to help you achieve the look pictured here. Finish off the costume with a fun hairstyle that complements the eccentric outfit and tie some ribbons to the ballet shoes for good measure. 17 Halloween Costume Ideas for the Whole Family What You'll Need Materials Iron-on adhesive such as Heat 'n Bond Polyester satin in assorted colors Harlequin templates White button-down shirt Iron White cotton fabric Basic sewing supplies White ribbon, 1/2-inch width, 2 yards Satin ribbon in various colors Ballet slippers White duct tape Instructions Cut out diamonds and iron onto shirt: For the shirt, make large and small diamonds: Following package instructions, fuse adhesive to wrong side of satin. Use diamond templates to trace shapes; cut out. Arrange diamonds to find a pattern you like on shirt. Iron in place. Make the bustle: For the bustle, hem edges of a 12-by-88-inch rectangle of white cotton fabric, sewing a 5/8-inch channel along one long side. Decorate with satin diamonds as described above. Use safety pin to thread ribbon through channel. Gather fabric together. Stitch a 12-inch piece of ribbon to each side of shirt. Tie ribbons on bustle to ribbons on shirt. Make the ballet slippers: For ballet slippers, cut four 30-inch lengths of satin ribbon (we used different colors). Use white duct tape to secure the ends into the insides of ballet slippers.
