Sleeve length: Short sleeve Size: 130cm Worn for one season. It's thinner than a sweatshirt, made of a material like mini-terry cloth, so it might be too hot in midsummer, but I liked it and wore it often. I bought them separately, but I mostly wore them as a set! The t-shirt has a loose fit and runs large. There are calligraphy stains in image 4 because I attend calligraphy lessons...
