This black Matteau The Square Maillot swimsuit proves that Ilona and Peta have been the gift that keeps on giving since 2015 - for the Brown's lady wouldn't travel around the world without packing her staple Matteau pieces. Each one is crafted in Australia from a stretch nylon fabric and features a square neckline, wide straps, a low-cut back and seamless front trim. You'll see us wearing our Matteau one-piece with Etro, Malaika Raiss and Saint Laurent on the beach front of our St Lucian luxury villa.
