I reviewed comments on what size to order and took the majority advice and ordered a large which is one size larger than I would have ordered. However, it was too big, especially in the bust. I take a size 8 and the large was too big so returned for a medium, have yet to receive so hopefully it will fit. UPDATE Received dress in smaller size and it does fit much better. However, it is still a little big in the bust. I am a size 8 dress, 36C and still had room in bust. I received many compliments on the dress, wore to a company holiday party and will wear it again to other functions. It looks fantastic in red.
