这款衬裙由金属丝和棉带制成。它本来会被一件额外的织物衬裙覆盖，以保护穿在上面的衣服。笼子的箍可以由鲸骨、手杖或钢制成。笼子的同心骨架可以用布带固定在一起，也可以完全包裹在织物中。这种底层结构所能达到的广度甚至比十八世纪的驮包提供的还要大。

This petticoat is made from metal wire and cotton tape. It would have been covered with an additional fabric petticoat to protect the dress worn over it. The hooping of cage crinolines could be made of whalebone, cane, or steel. The concentric skeleton of the cage would be held together with cloth tapes or it could be wholly encased in fabric. The expanse that could be achieved with this understructure was even greater than that provided by eighteenth-century panniers.
