Boxy Heather brown twead sweater

A dressbarn petite pullover sweater with long sleeve and a notched mock turtleneck collar. I'm not sure what knit stitch is used in the making of this sweater, but it has created a beautiful texture that shows the heathered brown tweed yarn to full advantage. It is made of 67% silk, 30% acrylic, 3% "other fiber".
