NWT Vintage Retro Style Dark Floral Dress

Vintage style calf length fitted at waist floral dress in a lightweight stretchy fabric. Sorry but I cannot find a tag which tells the materials. Colors are grey, purple and white flowers on a black background. Very pretty! There is a sash that ties either only across the front of the waist or the back. Also a hidden zipper up the back. MEASUREMENTS -across chest: 17" unstretched -across waist: 14.5" unstretched -top of shoulder to waist: approx 14.5" -Length: 44" Thank you for looking!
