Amour Verte fit and flair button dress

I purchased this, and it was too small for me at the time. It fits like a 10/12. It has bust darts and skirt darts. This dress is midi length and a true hour glass shape. There is no tag indicating material. I remember buying it because it was silk with a polyester lining and on sale. I love the pattern so much that I've just never been able to wear it. I do not want to take measurements. I'm just trying to clean out my closet. This is the kind of dress that you will need to unbutton the breast area to get on and off. There are no waist ties.
