Gray round neck and long-sleeved top with a check pattern. I bought it but never wore it, and it's been sitting in my closet. I'm selling it because I don't wear it anymore. Since there's still a temperature difference between day and night, I think it can be used during this time of year. I couldn't quite figure out the size notation, but I usually buy M size, so it's M. Please refrain from purchasing if you are very sensitive to details. Please purchase after understanding the item. - Color: Gray, Check pattern - Material: 25% cotton, 70% polyester, 5% spandex - Design: Round neck, long sleeves, slightly longer in the back #T-shirt #Cut and sew #Red check #Gray #M size
