First I'd like to say that there's a misleading guide. I usually wear 8 size for my top and 10 for bottom. Sizing guide says XS = US4 = UK8. However, when I got my parcel (I ordered 2 dresses (burgundy and soft black) in XS expecting it'd be my usual UK8) and tried them on I notices they were a little tight in chest and the length of shoulder seams was too short. So, I concluded XS = US4 = UK6 in reality! I reordered them in bigger size. Overall the quality's good and I expect these dresses'd become my Autumn to early Spring basics. A little downside they're a little long but I'm going to wear them with a stretching belt.
