This is an adult-sized cardigan from the overseas baby clothing brand EARTH. It is free size and unisex. It's a large size, so it will be loose-fitting on petite women, and it's a size that even average-sized men can wear. I haven't worn it after purchasing it, but it has been opened and stored, so I'm listing it as "like new." It was a made-to-order item when purchased and cost 14,850 yen.
