What is a peignoir?
Peignoir — is a light women's home clothing, which is a smart robe that is worn over a nightgown or underwear.

The term comes from the French word peignoir (from peigner — to comb hair). Originally, it referred to a cape that women wore during their morning toilette, styling their hair, and applying makeup.
In terms of design, a peignoir is a loose, flowing garment without any fastenings. It is often secured at the waist with a belt or thin ties at the chest.
Traditionally, such home clothes are made from delicate, translucent and flowing fabrics: natural silk, chiffon, satin, guipure or fine lace.
Main types

- Classic long peignoir. A floor-length model, often complemented by a small train, wide sleeves and abundant lace trim along the edges of the garment.
- Shortened (babydoll style). A mid-thigh length option, often flared from the chest down. Typically sold with a similarly styled short shirt.
- Kimono peignoir. A straight-cut garment with wide, cap sleeves, a wrap-over detail, and a fabric belt. It is most often made of opaque silk or smooth printed satin.
- Wedding (boudoir). A formal version made of white or cream lace and fine tulle, designed specifically for the "bride's morning" photo shoot.

What to combine with
Traditionally, a peignoir is worn over a silk slip, nightgown, or lace lingerie set to create an aesthetically pleasing home look.
The garment looks most harmonious when paired in a two-piece set. In such sets, the outer coverup and undergarments are made of the same fabric or feature identical lace trim.

In modern wardrobes, thick silk peignoirs in a lingerie style are often worn outside the home. They are worn as a summer duster, open over a basic top with thin straps and straight jeans.
The home look is complemented by boudoir shoes with a small heel and fluff (mules) or elegant silk slippers.
