This is a Showa-retro style kappogi (a type of apron). There are no specific size regulations, it's a free size, but it's about the size of a Medium, and you can adjust it somewhat with the ties. Available for immediate purchase. Feel free to negotiate the price. Purchased about 50 years ago and stored in a dark place with almost no use. Although it is unused, it is not as clean as new, so please be aware of this if you are sensitive to such things. When packing, I will take measures to prevent water damage and breakage before shipping. Showa Retro Retro Vintage Antique Japanese Modern Vintage Modern Kappogi Apron Japanese Clothing
