The T-shirt is navy blue, but there's a stain in the middle. It's hard to see, but it's also in the photos, so please take a look. The size is listed as M, but I think it's a size that would fit a child around 120 to 130 cm. (It's too small for my son who wears 140 cm.) I received it as a gift, so I'm selling it at a low price.
