You’ve probably noticed the frog button trend taking over the high street this autumn.
Also known as frogging, they’re decorative fastenings that look like a knotted toggle across jackets, tops, and blouses, giving an ordinary cardigan, puff-sleeve top, or outerwear a polished finish.
With a history in Chinese textile craftsmanship and later in European military dress, they’ve now filtered into everyday fashion as both a functional closing mechanism and a decorative detail.
Now of course, the high street has cottoned on, with affordable brands unveiling collarless jackets, statement coats and minimalist cardigans featuring these frog fastenings.
Rather than looking like you’re off to marching band practice, these stylish pieces have a vintage feel and update even the simplest silhouettes.
Wear one to upgrade jeans and a T-shirt, or pair it with a slip skirt or tailored trousers for the office. Brands like Ro&Zo, Tu at Sainsbury’s, and Topshop have created frog-button pieces in a variety of timeless and on-trend colours, with some as little as £20.
Whether you’re after a new knit to see you through the colder months or a smart layer for party season, we’ve rounded up the best frogging jackets and tops to shop now.
