The Bra Bather features a cylindrical design, extra cushioning, and a built-in frame. Bras should always be hung to dry, and never put in the dyer! Please keep in mind that if a bra is put in the washing machine, even in the Bra Saver Wash Bag, the bra runs a higher risk of the underwire coming through/breaking/bending, the fabric deteriorating/snagging/ripping, and the foam rippling.
