Arena has announced the acquisition of the global trademark rights for Diana, a less well-known Italian brand of swimwear founded in 1947. Diana started off with lingerie and began to produce swimwear in 1955. It created the first swimsuits and accessories for water polo. It subsequently introduced one-piece swim suits for women and suits for underwater swimming. It sponsored many national swimming federations. Arena will capitalize on a dual-brand approach in the areas of product development and geographical expansion.
