This is a multi-functional top from Takeo Kikuchi. I think it would be best worn over a shirt or long-sleeved t-shirt. It's an XL, but it fits more like a size L. It's thinner than a sweater, so it shouldn't feel bulky. The length is about 64cm, from armpit to armpit is 54cm, and the shoulder width is about 49cm. The color is a slightly deeper navy than in the photos, similar to the color in the shaded areas. There is some slight wear from use, but it has only been worn a few times and is in clean condition with no noticeable flaws.
