I have two M&S high impact sports bras the same as lisas shown above but just different patterns. Although they are difficult to hide under clothes like you have to wear tshirts alot, they give your boobs a nice shape under the clothes, I got a 34D and 36D in both and ended up sending the 34 back as was too small at first.
I think now i would fit in 34 as swelling has gone down so this has extra room (36d) but if youre thinking to go bigger or smaller deffo go bigger. Im happy with the extra room as oppose to it being too tight x
