CHANEL Black & Navy Check Plaid Short Sleeve Top Sweater Size M Cotton Blend (65% cotton, 35% polyester).  Medium weight knit with some stretch.  Pullover.  Classic basic - goes with navy and black.  Per fabric care tag, machine washable. Neck is a cross between a crew and a boat neck. Price reflects that this sweater likely has been washed as there is some gentle wear uniformly across fabric - not site-specific pilling.  Listing price reflects this condition.  Very fine solid ribbing around hem, neck, and sleeve bottom.  Small intertwined CC Chanel logo stitched close to hem.  Approximate measurements taken flat unstretched:  21 1/2" down center back, 17" underarm to underarm.
