Can be worn with both the pink and bear pattern sides. It's reversible, so there's no tag. Since there's no size indicated, I measured it. I think it's probably 12M. Length: 31 cm Width: 18 cm Sleeve length: 28 cm Shoulder width: 25 cm Please note that there may be some errors due to amateur measurements. It was a gift, but my child quickly outgrew it, so it's only been worn about twice. As you can see in the 7th photo, there's a faint stain. It's barely noticeable. I think the material is cotton. I've home-cleaned it with baby detergent in a laundry net. It's cute and can be worn on chilly days or paired with different outfits because it's reversible.
