Hey hun, I had 800cc and I found that the M & S one with the zip at the front really supportive and comfy…it also doesn’t come up too high and if you check my pics it reallyyy pushes my boobs up lol. I also bought the M & S post surgery bra; it’s mainly for ladies who’ve had re constructive work but it’s really supportive too and is also seamless for added comfort. It’s ideal to wear with lower cut tops too when you start going out again
I also got a Macom with a 38 back band which is a bit of a squeeze lol but I find it really good for sleeping in…keeps my boobs in place hah
Oh, I measure 36HH at the moment so that might give you an idea on size xx
