Medi Sheer Bat Sleeve Mixed Fabric Top or Cover-up

Mixed fabric with satin-like material on the top and a body of light, sheer printed fabric. Sunny bright yellow with shades of grey, black, and white. No materials tag. It looks like a European size 40 but it runs smaller. I wear a medium and this is a bit tight, so probably best suited of a size small or size 6. Measures about 14 inches across just below the satiny insert and about 26 inches in length.
