The color is black. I wore it once, and then I didn't have many chances to wear it, so I kept it in a drawer. I'm selling it because I've outgrown it. Would it be suitable for formal occasions? The size label has some yellowing, but the blouse itself is clean with no fraying or stains. Thank you. Size: Width: 41 cm, Length: 49 cm Sleeve length: 47 + 13 cm (The 13 cm is the folded-over part). You can adjust it to fit your arm length. It's a blouse, but I think it could also be worn as a light jacket.
