This is a top from GU. The color may appear different depending on the person, but I think it's reddish-brown, khaki, reddish-purple, or brown. The sleeves are long enough to cover the upper arms. The fabric doesn't feel flimsy; it's quite sturdy. Therefore, it would be perfect for spring, early summer, and autumn. Length: Approximately 50 cm Width: Approximately 39 cm I've worn it a few times. It's used.
