I had m&s zip up front, Asda and macom. Macom was by far the comfiest! More expensive but definately worth it, I got 2 so cud wear while other was in washer! I had my op in April n still wear my macoms to bed every night, I don’t want my boobs to sag and the macom keeps them nicely in place. Another good thing is after washing they go back to original size so they still fit after the swelling has gone so no need to buy different sizes. You can usually pick them up off eBay if u don’t want to pay a lot x
