Peignoir
A peignoir is a lightweight dressing gown, typically sheer and made of silk, rayon, or nylon. The term is of French origin, deriving from the verb peigner, meaning "to comb." It is generally a woman's garment and is intended to be worn while performing morning grooming rituals, such as combing one's hair and applying makeup.
Peignoirs are often distinguished from bathrobes by their delicate fabrics, shorter length, and more decorative details, such as lace, ribbons, or embroidery. While bathrobes are primarily functional for warmth and absorbency after bathing, peignoirs are more decorative and often associated with boudoir attire.
The garment became popular in the late 19th and early 20th centuries, often as part of a matching set with a nightgown or chemise. It continues to be produced today, although it is less commonly worn than it once was.
