I find dress shopping difficult and dress shopping online even more difficult because of my shape. I am often a large (or a tight medium) up top and a medium for trousers/skirts, which makes for a challenging dress fit. For this dress, I went for a size 14 and it fit like a glove (in the best possible way!). I wore this to the Westminster Abbey Carol concert and it was classy, warm (though I did add a pashmina), and best of all made me feel so confident and beautiful. The colour is a bit darker in person but I would absolutely recommend.
