"The uninitiated, a gilet (otherwise known as a vest in the US) might seem like a rather pointless item of clothing, akin to fingerless gloves or snoods. However, this garment was in fact born out of practicality. The grandfather of the modern gilet is believed to have first appeared around the 15th century and was then known as a “jerkin”. A sleeveless peasant jacket, usually made of leather, this trusty companion kept the wearer warm while allowing unimpeded movement for those out working all day.
Fast forward to the 21st century and things have moved on considerably."
