This is a ribbed knit from Coen that I purchased on ZOZO. It's a polyester blend, not wool, so it's not too hot and I bought it thinking I could wear it for a long season. I've only worn it twice and it's in beautiful condition. It's not hot, but the fabric is soft and not cold, so it seems like I could wear it in the winter too. The ribbing is cute. It's a size M, but I think the fit is quite relaxed. I bought it for just under 3000 yen.
