My maternity and BF were underwire bras. They were fantastic and the underwire was not wire as such but some special material designed for comfort and support. I will be back to edit later and let you know what brand they were. They were pricey. I only had 2 and they lasted all pregnancy and BF, it was all I would wear and the I paid them forward to another BB member


ETA: It was an Anita drop cup bra 5068. They were the most comfortable BF I had ever worn, I was quite big too, ended up a 32E from my usual 32C. I ended up buying the from an OS seller at a fraction of the cost of what you can buy them here after I got professionally fitted at my local bra store.
