Made in Portugal   About Organic Basics Organic Basics, a sustainable fashion brand based in Denmark, was founded by four Danish guys in 2015. They were tired of owning poorly designed and expensive underwear made by big fashion labels. Organic Basics was born out of the idea of fighting against the current fast fashion industry and its poor environmental standards. The brand aims to get consumers to switch to higher quality, organic and long-lasting clothing. The materials are natural, renewable, recycled, biodegradable and/or low-impact only. The design aspect of the brand is minimalist style paired with timeless design, combining high quality and the best organic fabrics. This makes the brand stand-out.
