What is a sheath dress?
Sheath dress A sheath dress is a slim, figure-flattering dress that traditionally lacks a horizontal seam at the waist. To understand the design of a sheath dress, it's important to note its cut: its tight fit is achieved solely through a system of vertical darts on the front and back.

Historically, this style evolved from the straight dress of the 1920s. The silhouette became iconic in the 1930s and 1960s thanks to the looks of Edith Piaf, Jacqueline Kennedy, and Audrey Hepburn, especially after the release of Breakfast at Tiffany's.
Today, it's a staple in women's wardrobes. The dress looks equally appropriate in formal business attire and evening wear.
Distinctive features
The silhouette's key feature is its close or semi-fitted contouring without creating excess volume. The cut creates an hourglass silhouette even on figures with a slightly defined waist.

The classic version ends just above or slightly below the knee, creating the so-called French length. To ensure freedom of movement, a narrow skirt always includes a vent or slit at the back.
The traditional cut features no collar or sleeves. The neckline is typically a deep round, scoop, or boat neckline. A long, concealed zipper closure zips up the back.
Sheaths are made from dense, shape-retaining materials. Wool crepe, gabardine, heavy cotton, and jacquard are most commonly used. Modern suiting fabrics include 2-5% elastane for added comfort.
What to combine with
For a business-ready look, pair a sheath dress with a structured single-breasted jacket. Classic pumps with a 5-7 cm heel and a rigid tote bag complete the look.

To create a smart-casual ensemble, the formality of the style is softened with a voluminous, long cardigan or a straight trench coat. For footwear, choose leather loafers, brogues, or minimalist basic sneakers.
An evening out calls for a statement piece. Large earrings, a statement necklace, or a classic strand of pearls are ideal. High-heeled shoes (stilettos) and a sturdy minaudière clutch complete the look.

To visually correct proportions, wear a sheath dress with an unbuttoned straight-cut coat or a long vest. This technique creates an additional vertical line, visually elongating the silhouette.
