This is a round-neck blouse. It's the type you just throw on. It's made of polyester material and feels smooth. There's no feeling of tightness. I think it would be cute to wear with a tank top. Please note that the measurements are approximate due to being measured by a layman. There are no noticeable stains or frays, but since it has been worn, there may be some unnoticed stains or frays. I hope you will understand and purchase it.
