This is a thin knit jacket recommended for spring and summer. It has no lining and feels cool, making it easy to wear. There is a stain near one of the pockets, but it's not very noticeable. Please check the photos. It's wrinkle-resistant and lightweight, so it seems like it would be useful to keep in your bag for when it's a little chilly or for air conditioning対策 (measures against air conditioning). It has pink and blue in it, giving it a cute atmosphere. It's hard to see in the photos from a distance, but please check the close-up fabric photos. It's a jacket that you can easily throw on like a cardigan. The pockets are decorative. There's no size listed, but I think it's about a size M. 100% polyester
