The Tesco high impact sports bras are very good,lots of members have the Macom and really like it,others have just gone for the Tesco or Asda bras,and felt that they had adequate support and comfort,The Tesco and Asda bras are not expensive,so you could actually get a couple of back sizes to see which ones feels better,you will probably experience swelling post op,so I think having 2 sizes,would be better,if you don’t mind the expense you could go for the Macom in 2 different back sizes,I believe from what I have read on the forum,the cups stretch to fit the breast,xxx
