I never buy clothes online, because I prefer trying them on. However, I took a chance and I'm glad I did. I got a 5/6 and it fits like a glove. It hugs my torso and flares out at the narrowest part of my waist. It looks very cute with black tights and chunky black heels.

As other reviewers said, the fabric is a little weird (kinda stretchy, but stiff) so it won't be a great sundress, more of a date-night thing.
