A peignoir is a luxurious and comfortable garment, often made of soft fabrics like silk or satin, designed to be worn over sleepwear. It resembles a long robe or dressing gown, featuring flowing sleeves and a loose fit that allows for ease of movement. The peignoir's elegant design and delicate details, such as lace trim or embroidery, add a touch of sophistication to the wearer's bedtime routine. It provides a sense of relaxation and indulgence, making it the perfect attire for lounging or getting ready for bed in style.
