This is a slightly fuzzy cotton material suitable for fall and winter. It's not very thick, so you can wear it as is in the fall, or layer it with a turtleneck shirt for warmth and style in the cold winter. I think you can wear it until early spring. It has a cute three-quarter sleeve design. I've only worn it a few times. It was difficult to capture the actual color in the photos. I apologize for any inconvenience. The colors are navy and dark brown with navy lines. M size 100% cotton Length: Approximately 83 cm Sleeve length: Approximately 42 cm
