A second on Natori bras, I'm wearing a feathers one today. I find them usually at Nordstrom Rack. Calvin Klein is also good for comfort and looking good under clothes without being too plain/ugly. True & Co. also have a good selection but they are not really cheap.
For fun and/or just for myself bras, I have liked Playful Promises, Agent Provocateur, La Fille d'O, etc.
