Thank you both for your replies! I took mine back n kept the same back size but got a cup size up. I’ve got my Macom coming tomorrow n also got that in a 34 (my back size). I never knew it could be so much hassle n hard work buying a bloody sports bra!! Might go back again from tomorrow til Thursday as my op is on Friday, so my time is starting to run out!! I guess I’ll soon find out either way if they fit xx
