vest

A vest is a sleeveless garment worn on the upper body. It is designed to be worn over a shirt or under another layer and does not cover the arms. In formal attire, a waistcoat is a type of vest that is typically worn with a suit. In American English, the term vest often refers to a sleeveless outer garment, while waistcoat is more common in British English.

Vests come in many styles. Knit or fleece vests provide lightweight warmth, while down or synthetic-filled vests add insulation without bulk. Padded or quilted vests serve as outerwear for outdoor activities. Athletic vests may carry gear, and safety vests in bright colors improve visibility. Materials range from wool and cotton to nylon and polyester, and closures can be buttons, zippers, or drawcords. There are also specialized versions such as life vests (personal flotation devices) and high-visibility vests used in work environments.

Vests also have non-clothing meanings. In law and business, to vest means to confer rights or ownership that become effective over time, such as stock options vesting after a set period. Etymology traces vest to Old French veste meaning garment. Across regions, usage varies, but the basic concept remains a sleeveless upper-body garment, whether for fashion, warmth, sport, or safety.
