More Sustainable Fashion Brand Offers This April 2025

"I founded ESSĒN in 2016 as a response to a fashion cycle that overproduces more than it carefully crafts, chases trends more than it determines classics, and wastes more than it sustains," says founder Marre Muijs. The shoes and accessories brand, which limits its production runs and uses low-waste cutting techniques, eschews the fashion calendar in favour of a single, permanent collection.
