Hi, I have been wearing m&s post surgery bras since day one, a rather unattractive beige one for the first 10 days then asda sports bra (pack of 2) since then. Mine are healing brilliantly and had no problems with support. I have also bought but ditched m&s zip up front bra, too tight can’t wear much over the top, and some support bras from matalan which didn’t cover enough of the cup. Xx
