This is a tweed jacket from nano universe. Color: Navy Size: M I purchased this several years ago and wore it multiple times over long sleeves. As shown in the fourth photo, the bottom hook is coming loose. Also, as shown in the seventh (front) and eighth (inside sleeve) photos, there are some pills and loose threads, and while there is some wear and tear, it's not very noticeable due to the dark color, and I think it can still be worn for a while. You can also wear a thin knit underneath, so I think this jacket can be used from now until winter.
