I wish I have bought this bra when I was pregnant, it ticks all the boxes, comfortable, supportive, no underwire and seamless! It really does live up to its name. The material is soft against the skin, and surprisingly, quite breathable.
To have 4 hooks at the back leaves quite a lot of room for adjustment, I am a M, and I have used the furtherest hook and the second row. I have used this bra more than my other maternity bras. It has lasted all through nursing bub and I still wear them sometime now when I feel like to have a wire free day:-)
The colour is quite subtle and it is invisible under clothing, very comfy!
