Thank you for viewing. It's unclear if this is sportswear or something else, but it looks easy to move in! It's labeled as a US size S, which seems to correspond to a Japanese size M to L. Please refer to the photos for the length. *Please purchase after confirming the profile and photos. I usually ship within 1-2 days. There may be times when this is difficult. I will also take care to package the item neatly. Please feel free to ask if you have any questions. The shipping method may be changed.
