I've cherished this item since I bought it because of its wonderful silhouette, and I've worn it for many important occasions. I loved its timeless design, but I'm selling it due to changes in my body shape. The material contains wool, but the fabric is thin and unlined, so I think it can be worn from late spring to autumn/winter. I think it will be warm enough if you wear tights in midwinter.
