This is a women's XS size T-shirt. I bought it for myself, but it felt a little small around the armpits, so I tried it on my child, and it fit perfectly. In terms of size, I think it can be worn by both boys and girls who are around 155-165cm tall. The color is navy. No name written on it. Although not very noticeable, there is a slight ballpoint pen mark on the maple leaf mark. I will sell it to someone who understands that it is a used item. #Adidas #Women's #XS #Navy
