EXCLUSIVE AT NET-A-PORTER. Peony was born out of a "life-long love affair with the ocean," and uses eco-friendly practices to help keep the sea beautiful and healthy. This polka-dot swimsuit is made using abandoned fishing nets and nylon waste from around the world. It's lined for opacity and gummed along the bandeau neckline to keep it from slipping. The pintucked bodice and cutout back are really pretty touches.
