This is a competitive swimming suit made by MIZUNO. It features low resistance, water repellency, and high-stretch material. The water repellency on the fabric surface is achieved through extremely fine uneven processing, which streamlines water flow, resulting in low resistance. This swimsuit is made of stretchy material that stretches well and fits the body. It also has cup hook receivers, so you can easily attach your own cups. The size is women's M. Because it's a competitive swimsuit, the fit may feel tighter compared to fitness swimsuits, but the arms are very easy to move, which is a hallmark of MIZUNO models. There is a feeling of use, such as from fibers, from actual use in the water. Please understand this before purchasing. #Halloween on Mercari
