Well this nightgown is so dainty, soft and innocent looking. Big collar, trimmed around the edges with white lace. 4 soft satiny buttons are the closure. Open the rest of the way down. It's got to be all cotton. It feels like old school cotton. The Union Label is printed on the back side of the care tag. 65% polyester and 35% cotton. Size is small. Saramae is the brand.
