I have the Mya bras so comfortable, ok I haven’t tried any of the others so I can only comment on the one I wear. Its so soft I feel very well supported the cup size just goes along with whatever size my boobs have changed to without the feel of loosing any support and I haven’t had to fiddle around with the straps when this has happened either. I was completely sold on the Mya bra when my PC handed me one to look only to be told after I had chosen to have then it was actually my surgeon choice of bra.
Hope all goes well for your daughter you must be very concerned to, my daughter went in the same time as me and I was more concerned about her as no matter how old they are they are still our little girls. I wish both of all the best. Xxx
