This isn't formal wear, but I wore it once for a funeral after removing the fur, and it's been stored in the closet since. There are no noticeable stains, and the condition is good. The color is a dark solid gray, so I think it can be worn for mourning. The size is 9AR, so I've listed it as a size M for now. When shipping, I will fold it up small, so please be aware of creases. Due to the nature of the fabric, it tends to attract fine dust, so please be aware of that as well. Measurements (laid flat, approximate): Length 97cm, Shoulder width 40cm, Sleeve length 57cm, Bust 46cm. Color: Gray系 (Gray-based) Stains, tears, odors, etc.: None
