I found two bras I like at Motherhood Maternity. Their large store in Dallas off of 635 (near the Galleria) had a better selection than any of the mall stores I looked in.
One is a sports type bra that I like to sleep in.
The other could almost certainly pass for a "normal" bra and is easy to wear with T-Shirts and has an underwire. The snaps are on the cups. I think they had it in nude and black. It was a little pricier than their others, if I remember correctly, it was around $45.
Hope this helps!
