The waistcoat: a royal decree, a survival tactic, and a master of disguise

In short: Why do we still leave the bottom button of a waistcoat undone? It isn't just a fashion faux pas or a royal quirk; it is a functional solution to the physics of riding and the evolution of tailoring. From 17th-century royal decrees to 19th-century dandyism, this garment has survived by adapting its purpose.

The waistcoat's journey began as a statement of national identity. In 1666, King Charles II of England championed the 'vest' as a way to move away from dominant French fashions. While the garment was influenced by Turkish and Persian styles, it was officially introduced to teach the nobility 'thrift.' Though it only remained popular in elite circles for about seven years before the King reverted to French styles, the waistcoat persisted in the provinces and was reintroduced across Europe in 1678.

The name 'waistcoat' itself carries layers of debate. One theory suggests it was a 'waste-coat,' made from leftover fabric from tailoring a two-piece suit. Another theory posits it was named for the cut of the garment, which was tailored at the waistline. During the 17th century, soldiers even wore waistcoats as a practical reuse of old uniforms, turning worn-out overcoats inside-out to reveal a contrasting lining and removing the sleeves.

The famous tradition of leaving the bottom button undone is often attributed to the expanding waistline of King Edward VII, but this is a myth. The practice actually originated to prevent the garment from riding up or wrinkling when the wearer sat on a horse. Because modern waistcoats are cut lower than their predecessors, a fastened bottom button would cause the fabric to pull and bulge. This specific convention only applies to single-breasted day waistcoats; double-breasted and evening varieties remain fully buttoned.

By the 19th century, the waistcoat underwent a radical transformation. Following the French Revolution, anti-aristocratic sentiment stripped away the elaborate silks and heavy embroidery of the 1700s. It shifted from being a centerpiece of visual display to a 'foundation garment' that provided a structured, figure-enhancing base for the frock coat. Today, it remains a staple of formal wear, with specific rules—like the use of white for 'white tie' and black for 'black tie'—maintaining a sense of continuity.
