I bought this at GAP a few years ago and my child wore it. It looks like knitwear, but it's 100% cotton. The size is listed as XS (110), and I think the size is as stated. Measurements by a non-professional (laid flat): Length 44cm, Width 36cm, Shoulder width 31cm, Sleeve length 40cm. I think my child wore it more than 10 times, so there is some fading overall (especially on the navy ribbing). The navy looks a bit darker in the first image, but please check the other images for the actual color, as it is faded. Also, there are small pills, although they are not very noticeable. There are no stains or tears, and in my subjective opinion, it doesn't look shabby enough to prevent normal wear, so I think it can still be worn. Please understand that this is used children's clothing.
