Nursing bras

Twelve years ago I opened up a Hanes catalog, found 2 nursing bras, and ordered the one without underwire. I am still wearing that bra. I bought nursing bras when I was pregnant with Tommy, two of them, and they suck.
One was almost a sports bra style which was fine, but when you unhook one side, the other side shifts and pulls the nursing pad off center. Not great when feeding on one side causes letdown on the other. Also, the stitching at the bottom was decorative and scalloped and when you're wearing the thing 24 hours a day scalloped stitching is like a saw blade digging in.
The second was a sleep bra that I still sometimes wear, but it was the thinnest cotton (like granny panties) so it offered no support. And it was a cross over style so when I lied on my side the top boob all but fell out the middle.
Why is it so hard to find a wire-free nursing bra that isn't sexy (I need comfort, not looks), has support, will hold a nursing pad, and doesn't shift or lose support when you open it? If I'm going to wear this thing to sleep, it has to be comfortable. It can be as sexy and cute as it wants to be; nursing pads and milk stains will kill the effect. I want a bra where the whole cup doesn't come away, just a panel over a cup with a whole. I want a bra with support (no seamless t-shirt bras) but without wire. And I want one that stays put and doesn't dig in. I don't care if it's hideous, I need it for function. Demi bras and sport bras and lace and push up and padded and plunge front and satin dome no good. Cotton/lycra, one hand cup hooks, support, comfort. That's all I ask. WHich is probably why I'm wearing a discontinued 12 year old bra. Ugh.
