First the warning, then the description. This is a NOVELTY item, as such, it can come undone and fall off with little or no effort. We suggest you wear it over a shirt to avoid any potential embarrassment. That said, this product is adjustable and packed in a polybag of 1 piece. Perfect costume accessory for those Beach, Surf, Tiki, Luau or Hawaiian Theme parties. Please order in increments of 1 piece.
