I found the best nursing/maternity bra was Anita 5068. It's like a normal bra, has underwire. Only difference is you can use it for BF as it has the drop down cup. These were by far the best investment I made. I wore them pregnant and BF and only ever wore these, I had two, one black and one white. I bought mine online from a US store. I am a funny size pregnant and BF as well. I was 12E (my normal size is 10-12C non pregnant)and these bras did the trick. They are a microfibre sort of material, no lace and really just looked nice on too.

I wore them all the time and they were still good quality enough at the end to give away, in fact another BB member snapped them up.
