What is a sheath dress?
Sheath dress — is a narrow, figure-flattering women's dress of a straight or semi-fitted cut, traditionally without a horizontal seam at the waist.

The style gained popularity in the 1920s and 1930s. Its status as an iconic wardrobe staple was cemented in the 1960s thanks to a black dress by Hubert de Givenchy designed for Audrey Hepburn.
The silhouette is formed exclusively through a system of vertical darts. This design allows the garment to follow the curves of the body without being too tight and maintaining a strict geometric shape.
Distinctive features
The classic version is midi length - strictly to the knee, slightly higher or slightly lower.

Traditionally, a sheath dress is sleeveless or has short sleeves. The most common necklines are boat neck, crew neck, or bob neck.
To create the right architectural silhouette, dense, shape-retaining fabrics are used. These include wool crepe, heavy cotton, tweed, and suiting blends.

The style is characterized by a strict minimalism. There are no patch pockets, draping, or frills, and a neat back vent at the skirt allows for freedom of movement.
What to combine with
For a business wardrobe, pair the dress with a structured straight-cut or fitted jacket. Classic pumps and simple jewelry complete the look.

For an evening out, the basic silhouette is complemented with accent pieces: large metal earrings, necklaces, or bracelets. For footwear, choose stiletto heels, and the everyday bag is replaced with a sturdy clutch.
A sheath dress pairs harmoniously with a classic trench coat, a straight-cut double-breasted coat, or a robe coat. According to traditional styling rules, the hem of the outerwear should completely overlap the length of the dress.
Modern sleeveless styles lend themselves to layering. They're worn over a thin wool turtleneck or a basic cotton shirt, complemented by chunky-soled loafers or brogues.
