Rihanna's costume designer, Adam Selman to launch own label Adam Selman will debut his first collection during New York Fashion Week this September. Who'd have thought that British High Street chain River Island would inspire a New York Fashion Week debut? Well that's whappened after Adam Selman - popstar Rihanna's costume designer - got a taste for retail after collaborating with the chain as part of the singer's union with the store. As Rihanna's closest sartorial collaborator for the past two years, Selman was introduced to her through his stylist boyfriend Mel Ottenberg. He acted as head of design for her range with River island, and is more than capable of running up outfits for the singer in a matter of hours. Now, Selman is spreading his wings with his debut collection for spring/summer 2014, which will be revealed on September 5. WWD enjoyed a preview of the range, which is described as having a heavy swimwear component but is ultimately 'wearable'. Unsurprisingly, there's no sign of the bejewelled bras he created for her to wear to Carnival in her native Barbados (see below), but Selman described his collection as: "sexy. It's that fantasy woman but it's also sporty. Photo: Splash Selman hopes his debut collection will be picked up by Opening Ceremony, Net-a-porter and Barneys New York.
