70s Keyloun hostess maxi dress. The Marigold yellow turtleneck top feels like a polyester knit with back zip closure, and hooks at the back of the turtleneck. There is a removable sash that coordinates and is the same fabric as the boldly patterned quilted skirt. There is some dirt on the underside of the hem. I have not tried treating it. Laying flat measures 56 inches shoulder to hem, 16 inches armpit to armpit, 13.5 inches straight across the waist and 22 inches across the hip.
