OK, so it's a white cotton bra with four hooks in the back, basically the ugliest bra in my collection.  However, the wide straps are supportive, the lack of underwire doesn't bother me (and I prefer underwire for all my bras), and this bra is super comfortable to nurse in.  Of the three nursing bras I have, this is the most supportive and most comfortable.

I was fitted for this bra at the maternity shop in the hospital and felt pretty grim that I was wearing the largest cup size they carried (this was the only bra they had that fit me) but I liked it so much that I came on Amazon for another. I was very pleased to see that Amazon carries additional bands and larger cups than the hospital shop.

Pre-pregnancy I wore a 32E, and this bra in 34I fits very comfortably and provides a good shape under my clothes.  Combined with a cotton nursing pad, I don't look cold, either.  I like the simple hook-eye for the nursing cups, too - much easier than all the weird snaps the other products have.
