Multi color sparkle black tank top

This is a gorgeous tank top, excellent condition, no size tag, but I would say approximately XS. It was bought from European boutique. The straps cross on the back and they are double on each side. The tank top is overall a black color, but it features multi color threads that appear silver at times, multicolor at times, or just black depending on the angle and how light hits it. Soft, light and stretchy fabric. Dress it up or down. Comes from a pet/smoke free home and feel free to ask about measurements!
