This is a Body by Victoria tank top made of nylon, lycra and spandex. Size small. It is very soft and comfortable, also has adjustable shoulder straps for adjusting to your comfort level. Beautiful spring/summer colors. You could wear this under a shirt or alone. So soft that you could sleep in it! The interior has some weird kind of stitch going down the side, under the arm pit area...this is because it is a SEAMLESS style, and those are where the fabric was joined. I took photos of the inside to make it better to understand - whatever they did, definately made it more comfy!!!
