Freya Pure.
There just aren't many underwired nursing bras available, so I thought I'd give this one a try. I love it! Just wish I'd found it a few months ago.
Of course with these you have to make sure you have the correct size so you don't give yourself mastitis or blocked ducts. I was fitted in Bravissimo, but I didn't like any of their soft cup nursing bras. They made my boobs much too pointy.
I haven't found them in any stores; I got mine here.
