Pattern Design: Solid Season: Spring, Autumn Zip/Buttons: Zip-up The fabric is suitable for spring and autumn, and I think it can be used as a light outer layer during this time of year. The sleeve length is also a little short, so I've included the measured length in the 9th photo. Also, it's light, so it won't be bulky to carry around. It's navy, although it's difficult to tell from the photos. This is a used item, so please consider purchasing if you understand this.
