This type of wide sash is worn as a waistband. It was originally worn by men in India, but has recently been adapted for men's formal wear. What is it called?

This pleated sash traces its origins directly to India, where its name plainly reveals its function. The word is an Anglicized version of the Hindustani term "kamarband," which literally translates to "waistband." In its original context, it was a practical and often colorful sash worn by men to cinch clothing at the waist. Its journey into Western formal wear began during the British colonial period.

British military officers stationed in India observed the comfort and practicality of the kamarband, particularly in the hot, tropical climate. They began wearing it as a cooler and less restrictive dining accessory, a welcome alternative to the stiff and heavy waistcoats traditionally worn with formal dinner jackets. This sartorial adaptation was brought back to Europe and gradually became an accepted part of black-tie attire by the 1920s.

Today, its primary role is aesthetic, designed to cover the waist and create a clean, smooth line between a tuxedo shirt and trousers. A key piece of etiquette is that the pleats should always face upwards. This tradition has led to the playful nickname "crumb catcher," based on the idea that the small folds could catch any food dropped during a formal dinner.
