This is sized for a child approximately 11-12 years old, around 152cm tall, so it may not necessarily be an XS size. I received this from my cousin, but I have never used it. There are small frays as shown in the photos on the chest and around the stomach. It has been folded and stored in a closet, so I don't think there is any odor. The tag is attached. Please refer to the photos to determine the material. I am not very knowledgeable. There is no dirt, rust, or damage to the collar decoration. *This is based on my personal assessment. I may have missed some details. Instant purchase is OK. Color: Navy系 (Navy-based) Material: Cotton Neck: Crew neck/U-neck Season: Autumn/Winter Condition: Some stains/tears/odor Thank you for viewing.
