onepiece

Onepiece was founded on a lazy Sunday in 2007 by three young Norwegians. In an effort to capture the essence of this carefree day in a single piece of clothing, the brand was born. The idea of sewing together a hoodie with a pair of sweatpants using a giant zipper ended up becoming the Original Onesie; the perfect Sunday uniform, but also a product solving the entire concept of comfortable clothing. Some said it would look stupid, many believed it wouldn’t last. Today, nearly 15 years later, the Original Onesie is still the very core product of our brand and our bestselling style. Onepiece is the jumpsuit specialist brand. We are a niche casual clothing brand with the world's biggest catalog of jumpsuits and onesies for men, women, and non-binary people. We’re constantly developing new limited designs, and timeless pieces for all seasons and (almost) any occasion.
