This is a Nike Dry-Fit cross-back sports bra in size S. It has been tried on and washed once, and used perhaps once, making it a beautiful item in almost unused condition. However, as it is a used item stored at home by an amateur seller, it may not be suitable for those seeking a brand-new item. [Size] The size is S, but it runs a bit small. The underbust laid flat measures 29cm (Photo 1), and the elastic band is quite firm. It was a tight fit for an underbust of 72cm. The cups are connected to the main body by thin plastic strings (Photo 4), but if you cut the strings, you can insert other cups. (It's possible that it's designed to be used with the strings cut off.) [Main Body Material] 82% Polyester, 18% Spandex As the material is soft, it will be shipped compactly folded without padding, using YuYu Mercari便. Thank you for looking.
