Womens beautiful tank top, M rutched black with blue tropical flowers

i dont know how to describe the texture of the fabric, the way it is sewn, so there is a close up picture if the fabric.shirred? this is 100% rayon, form fitting and very pretty. i think this is a small or medium but the way it is sewn gives room as it stretches. has a straight neckline with lettuce edges, sits just below belly button
