This sleeveless top is fashioned from a crepe-like fabric in very artistic shades of blue, with splashes of gold. It’s fully lined in black and could be reversible, as it is completely finished on both sides. It’s beautifully made and although there are no tags, I believe it is polyester. Measurements are: Shoulder seam to hem: 23” Armpit to armpit: 19” Side seam to side seam at hem: 21” Happy to answer any questions!
