How do I wash and dry this type of bra so it maintains it's shape?

I usually use bras that don’t have a molded shape, like these. I wash them in a lingerie bag and hang them on a doorknob to dry.

I bought one of those bras that has a molded shape. It’s not padded, but it is definitely stiffer and has a very definite shape, kinda like these.

How do I wash and dry this bra so it does not lose it’s shape? This was a $70 bra and I want to keep it looking nice.
