Viscose Linen Exposed Seam Blazer by Lafayette 148. It's a size 0, but it fits more like a size 2, as it is a relaxed fit. There is a double side seam, and I photographed the fabric with light behind it to express how sheer the fabric is. The blazer looks lovely with a belt over it or paired with suit pants. The fabric is absolutely gorgeous, as is the fit of the blazer.
