Yes, I have 5 Shapermint bras and they wash up beautifully. I place them in a mesh zip-up bag and wash them on permapress cycle with my undies and socks. I air dry them and they always return to their original shape.

Yes, Shapermint is machine washable either on delicate or a mild, careful cycle. I always place any of my items in a nylon bag that zips up and place it in the washing machine. I never, ever dry in dryer, always air dry on a rack or if you have a patio and the weather is great, on the railing outside.
