Spotted all over Instagram as the latest sparkle-tastic swimwear brand, Oceanus pieces are just built for a beach party. Hand-stitched in London, the brand aims to provide a safe and fair environment for all workers. Econyl — the fabric made from recycled fishing nets and old nylon — makes up the majority proportion of each garment, and the embroidery beading is biodegradable. The brand is striving for a zero-waste business model, so all off-cuts are used to make face masks or small accessories. The Callie White Embellished One-Shoulder Swimsuit (£280) has caught our eye, but we'd more than happily wear any piece from the brand.
