This is my favorite nursing bra!  I've had several others and having a bigger set of girls, I wanted a bra with:
1. Underwire support
2. Enough padding so that everything doesn't show but not too much so that it's stiff
3. Comfortable! (read- no itching or poking)
4. Pretty (I know this one seems sorta stupid, but I'm not the type to pay $40+ for an ugly normal bra.)

This bra met all of my requirements and to my surprise was not as firm as I expected.  I have another padded bra from Motherhood Maternity that was really stiff and hard to get out of the way.  This one peels back very easily so that my son doesn't have to deal with it hitting his chin while he nurses.  I was surprised also that it was pretty affordable considering it had everything that I needed, which is difficult when you have an F cup. I haven't had a problem with anything showing through and if I have it clipped, you don't even know it's a nursing bra.  I'll be getting another one probably soon.
