This is a long-sleeved T-shirt from AS KNOW AS Olaca. It's made of a soft material, so I think it's easy to wear. It was originally part of a set with a vest, but I'm not going to wear this long-sleeved T-shirt, so I'd like to pass it on to someone who will. The color is a light gray, or perhaps a light blue, please check the photos. I've also included a photo from the website. Here are the approximate measurements: Width: 70cm Length: 58cm The size is 5, which I believe is about a size 19. I plan to ship via Yu-Yu Mercari delivery. It will be folded for shipping, so please be aware of any potential folding wrinkles.
