I usually vary between a 0 and 2 in DVF but for this dress I was absolutely a 2. So thankful that they give the option of sending a 2nd sizes or I would have been in big trouble. If you have a bigger chest and are debating between 2 sizes - go up to the next size. Dress was a lot of fun and received a lot of compliments. I usually wear fitted dresses but this was a nice change.
