Everyone seems to use asda and tesco but it depends on what you’ll be doing in the 6 weeks lol. I’m now a 32GG so I’ve got to wear high impact ones. Any M&S ones should be cool though. But my advice is to get a macom bra and wear that until you feel up to going to town to be measured and try them on as there is no way to tell how you’ll fill up or how swollen you’ll be. Plus, I got 34f which isn’t too bad on the cup as it’s only a sports bra, it’s just a really snug fit! but the band hurts a but after a while. I’m 8 days po xx
