It's a quirky shirt coat, I think?! I'm not sure what to call it exactly... It's made of thin wool and has a unique design. There are buttons on both shoulders, and when you button them, the shirt's appearance changes. I used to wear it under a coat or as a light outer layer. The color is black, and it's slightly sheer. Length: 65cm, Pit to Pit: 52cm The tag says S, but it definitely fits like a M. It's back from the dry cleaners and doesn't have any noticeable stains, but there is some pilling. Please understand that this is a used item.
