Selections cover children and teens as well as adults. Examples list suggested ages (e.g., 5–12 years, 14–16 years) and adult sizes from X-Small up through 4X/plus sizes.
Collars commonly use hook-and-loop fasteners at the back of the neck. Bows may be mounted on a plastic headband with ribbon trim, and suspenders are often elastic with decorative buttons or adjustable elastic straps.
Darker clown looks use materials like black satin and layered polka-dot tulle, with trims such as candy-pink pompoms, gold trim, and tulle collars or armbands for a spooky effect.
Some jumpsuits are made from a jersey knit blend that stretches for comfort—one listing specifies 93% polyester / 7% spandex. Elastic cuffs and bands also add flexibility.
Tails may be sewn on or secured with hook-and-loop fasteners. Headpieces often fasten under the chin with hook-and-loop tabs, and shoe covers use elastic bands or ribbed ankle cuffs to stay on.
Easy-dress features include hook-and-loop fasteners down the center back, foam-backed hats with elastic loops, elastic cuffs and bands, and attachable shoe poms that secure with elastic bands.
