You guys over the pond don’t tend to use double letter sizes i.e. FF/GG, so your alphabet moves a little quicker than ours! All Curvy Kate bras start at a D cup and (most) go up to a K cup, all styles follow the same sizing pattern so once you know what your size equivalent is then you’re good to go.
