I have been wearing a 38C and usually ended up with quad boobs that I had to keep pushing under my arms . After trying on about 7 bras I bought the first one I tried on in a size 34D. It fits really well and boobage is now at least an inch more lifted but as the band is tight which is necessary it does show up more back fat, which is a bit disappointing and something I thought may happen.
It is a Prima Donna which I have never heard of and was £53 so not cheap but worth it hopefully. Will get used to it and then maybe buy some more.
Thanks for whoever mentioned Essentials in Preston which is where I went.
