This is a fantastic set by Eddie Bauer made from 99% cotton and 1% spandex. Has a sleeveless top with round neckline that can be worn by itself and if you should get chilly it has the same material and color with long and sleeves that you can wear open or button up. The color is charcoal grey almost black. I Love this !! Excellent condition!! Size med. Measurements are approximately lying flat pit to pit top 18" open top 19" buttoned.
