I've bought several styles of maternity bra for my pre pregnancy 12E bust, but this is the best by far. I was looking for support with comfort, and found this to have the best level of support for a heavy bust, while the flexiwire, sleek fabric, wide straps and band, heaps of hook and eye closures and easy clasp made it comfortable and functional. I sized up to a 12G post pregnancy to accommodate size changes and it fits well. I wish these were the first bras I bought!
