This is a cardigan with pockets, knitted with gray and white yarn. It's not thick, so it can be worn under a coat. In spring and autumn, it can be easily worn over a cut-and-sew or T-shirt. It has no buttons. There is some pilling in places, but I think it's not very noticeable. If you are concerned, please refrain from purchasing. If you have any questions, such as detailed size information, please feel free to ask.
