Hi Nicola I got a macom bra as you just need to know your back size to order rather than trying to second guess your final cup size. It is so comfy i bought another, they are expensive but personally i think you get what you pay for and they are worth it. You are spending thousands on new boobies so its best to look after them from the start! I also got M&S High Impact Sports Bra which zips up the front however i found it incredibly tight and uncomfortable straight after surgery, possibly because i didnt buy a big enough size! I know Asda do post surgery bra’s but not sure what they are like xxx
