I am between a size 6-8, and this fits me perfectly. It hugs my curves in all the right ways due to the corset bones from the top to the waist. It has underwire cups, so I did not need a bra. It never slipped down, And I never had to re-adjust. It is double-lined, and the fabric looks and feels expensive. I am about 5'7, wearing 4-inch heels, and the train hovered above the ground. The top has been slightly altered (not the size) to make the points a little more rounded. This dress is so simple yet elegant, and I received the most compliments on this dress out of the others I have previously worn.
