The chest area is made of mesh material. It's simple and I think it will go well with any outfit. This is a size S. It is a new, unused item that has only been tried on. I am selling it because the size did not fit. Below is the official size chart. Please refer to it. ■Size (The middle of the numerical range is the size that can be worn comfortably) Size S: Bust 66-78cm, Waist 60-74cm, Hips 76-100cm, Girth 130-150cm Size M: Bust 70-88cm, Waist 68-88cm, Hips 80-112cm, Girth 136-155cm Size L: Bust 80-98cm, Waist 72-100cm, Hips 92-120cm, Girth 156-172cm
