Describing a low-cut neckline that exposes the upper chest and sometimes the shoulders.
Décolleté describes a garment with a low neckline that reveals the upper chest and may expose the shoulders. In English it is chiefly an adjective, so it describes the cut of a dress or bodice rather than naming a complete garment category. French also uses the noun décolleté for the opening itself. The useful distinction is between describing how low a neckline is cut and specifying its shape. A low neckline may take different shapes, and the word alone does not tell a maker or fitter its exact outline, dimensions or construction.

This word is more common in fashion and beauty product copy than in vacancies. In skincare, it can also mean the area of the upper chest, so an advisor should know both senses. Search local jobs for “tailor”.
