I was told to get a size or two bigger because of the swelling that you will experience. The girls on here can recommend a lot of different bras. From what I have seen the most popular on here is the shock absorber. Asda also do good ones and there is also the Macom (1007) which is what I have ordered because I don’t know what my end result will be, it stretches to fit you you just need to know your back size.
I had a look at the M&S ones and they’re pretty good.
