Floral Boho long Black Maxi dress

Super pretty black long floral boho dress with long sleeves. No size or fabric tag. But I think it fits a medium. Fabric feels smooth and slinky. Scalloped detail at collar and zippered back. Fabric has a slight stretch. Never been worn. Sleeves are elasticized. Approximate measurements: Shoulder to shoulder:17” Pit to pit:20” Waist: 16” Sleeve length: 22” Pit to bottom of dress:42” Top to bottom of dress: 52”
