Vintage Shadowline Floral Peignoir Nightgown Set with Embroidered Accents Medium. This beautiful, vintage peignoir set is from the 70s and is a beautiful spring, summer print of blue and yellow florals. The nightgown and robe are 40-41" long so, depending upon your height, about midi length. The robe buttons up the front or can be left open to show the beautiful nightgown underneath. Very romantic and cottage-core. This peignoir set is in excellent pre-owned condition, showing no signs of wear. See photos for details and measurements.
