Self: 100% nylonContrast: 95% poly 5% spandex. Hand wash cold. Adjustable shoulder straps. Back hook closure. XIRE-WI150. X43046. Designer and founder Dierdre Roffoni created XIRENA based on her years of travel to the hippy town of Formentera, Spain. Inspired by the carefree lifestyle of the island, a collection of chic, modern, and sexy separates was born. In designing XIRENA, Dierdre draws from lingerie and swimwear to create a line that can be worn at home, on the go, or lounging on the beach. The simple shapes combine bold prints, vivid color, and metallic accents; these elements continue to act as the building blocks for the line season after season.
