Think that’s the same fabric as a macom like a compression bra I had the macom I bra was so comfy and kept them in place. You just need your back size and the cup size changes I was in a f bra after surgery then a e and now a dd as the swelling goes down you need a bra that adjust. I would recommend getting 2-3 as you need to change it every day x
I had the signature one for when I first had my op had mr Traynor so had no strapping. I found the i bra better week 3/4 as it was a little tighter and compact round my breast especially as my right one was still swollen. I used the ‘mybreast’ code. Check out the Twitter account sometimes put discounts on there. I had a few bras from marks and spencer found them uncomfortable also had a shock absorber I wore twice probably best for when you know what size you are xx
