The brand’s vast catalogue consists of one pieces, halter-necks, high-waisted, waist ties and bandeaus – all in funky colours and prints (as well as classic styles) – ensure there’s something for everyone.

As with many sustainable brands these days  – the best ones tend to not even include ‘sustainability’ in their marketing and let the materials do the talking. The main fabric the brand uses is ECONYL®. What’s ECONYL® you ask? Think of it as regenerated nylon. Nylon is a fossil fuel fabric, but ECONYL® (which has a very similar tactile quality) can be recycled, remoulded, over and over.
