Most costume mustaches attach with adhesive: self-adhesive or double-sided strips with peel-off backing are common. When mustaches are part of a hat or cap set, hook-and-loop fasteners (Velcro) or interior fasteners are sometimes used to secure the piece to the hat rather than directly to the skin. For best hold, apply adhesives to clean, dry surfaces.
The sunglasses in these kits are novelty plastic frames with smoke-tinted or yellow lenses and decorative prints. They are intended for costume use and are typically not rated for UV protection, so they shouldn’t be relied on for sun safety.
Hat-mounted beards and mustaches usually attach to the hat lining using hook-and-loop fastener strips or other interior fasteners that secure the facial hair to the hat instead of the wearer’s skin. This keeps the piece in place while worn with the hat.
Many listings use general sizing like “one size fits most” (often for adults) or simply label items as “Men’s” or “Adult.” Product details sometimes list suggested ages—examples range from 3 years and up, to 14 years and up, or are marked for adults—so check each product’s description for the manufacturer’s guidance.
