More about OnePiece

OnePiece is a Norwegian fashion brand that is said to have created the onesie slackerwear movement. It was established in 2007, and soon became a global phenomenon. OnePiece now has 10 Concept Stores, and over 1000 retailers selling the casualwear in over 100 countries. If you’re the ultimate slacker, who doesn’t like to get out of the house on the weekends - OnePiece is the brand for you! If you do get out and about but love the leisurewear look, then OnePiece is still the brand for you, as all items sold on the website are outerwear too - providing you with the ultimate crossover pieces for slouchy days.

Online, you’ll find Men’s, Women’s and Kids categories, though a lot of the stock is unisex. OnePiece makes clothes for every season, so if you enjoy the winter wear, you can get your favourite items in a cut-off, short version too! And it’s not just about the onesie, you’ll also be able to shop for underwear, t-shirts, jackets and accessories. If you like to keep ahead of the fashion pack, you’ll love the LookBook pages of the OnePiece website, where you can trawl through loads of inspirational photography of the latest styles. LookBooks are split into categories such as ‘Festivals’, ‘Men’s Casualwear’, and ‘Women’s Street Style’.
