Purchased overseas several years ago and worn 2-3 times before being stored. It's labeled as size S, but it can also fit like a size M. It's suitable for leisure activities near water, such as wearing it over a swimsuit, as well as for everyday wear. It has pockets and removable shoulder straps. There are no noticeable stains, but please understand that it is a used item that has been stored for a long time. Thank you.
