Frog button fastenings, known as frogging, have become the defining autumn trend across the high street. These decorative closures, which resemble knotted toggles, now appear on jackets, tops, and blouses, adding a polished finish to cardigans, puff-sleeve tops, and outerwear.
Originating in Chinese textile craftsmanship and later adopted in European military dress, frogging has transitioned into everyday fashion as both a functional fastening and a decorative element. Affordable brands have embraced the style, offering collarless jackets, statement coats, and minimalist cardigans.
Styling and availability
These pieces offer a vintage feel that updates simple silhouettes without evoking marching band uniforms. They can elevate jeans and a T-shirt or be paired with a slip skirt or tailored trousers for the office.
Brands including Ro&Zo, Tu at Sainsbury's, and Topshop have released frog-button items in timeless and on-trend colours, with some priced as low as £20. The selection spans knits for colder months and smart layers suited to party season.
