For casual / lounging kind of wear I like the Medela comfort bra. I have yet to find a really supportive one for everyday or more active wear. I have heard that the Helena or Fiona sports bras are good. www.fitmaternity.com had some good suggestions.
Re: nursing bra recommendations please
I like the one I have from Destination Maternity (A Pea in the Pod brand, not Motherhood brand) better than the Medela one that I have.
I've heard good things about Bravado.
