This is a competitive swimsuit made by ARENA. It's a high-quality model with 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 extends well and fits the body. Furthermore, it has cup hook receivers, so you can easily attach your own cups. The size is Ladies' O (XL size). There is a feeling of use, such as wear and tear of the fibers, and fading of the inner lining around the chest area from actual use in the water. Please understand this before purchasing. #Halloween on Mercari
