This is not new. It was used by a child and has been washed at home. Please be sure to check the images. It's a thin sweater. There's a button at the neckline, but it's a removable button for the collar (for the collar in image 6). The striped detachable collar was not specifically made for this and was purchased separately (image 7). I think both collars can be used with other clothes. Please purchase if you understand that this is a used item. It will be folded and shipped via post. Compression may be necessary depending on the thickness. #KidsClothes #Sweater #Knit #150cm #DetachableCollar #Tops
