All-over print, red long-sleeved T-shirt. Looks cute worn as an inner layer. Slightly stand-up collar, stylish. The manufacturer is unknown as there's no tag, but I think it's a very unique pattern. Definitely recommended as a pop of color under a dark outer layer. It's a men's S size, but the fabric stretches, so it can also be worn by people who usually wear M or L sizes with a slim build.
