Excellent preowned condition White House Black Market button-down dress shirt. Materials are 78% cotton, 19% nylon, and 3% spandex. I really loved this blouse! It is very flattering for people with busts on the larger size. I changed sizes, so it doesn't fit me anymore. Feel free to message with additional questions! Approx. Measurements: Pit to Pit: 20.5 inches Waist: 17 inches
