Rihanna is back on tour! The pop star kicked off her summer Loud tour in Baltimore this weekend, where she revealed some interesting new stage costumes. For her opening number, "Only Girl (In the World)," RiRi cinched on a metallic blue silk lame jacket by Jeremy Scott, only to reveal a bedazzled two-piece when she whipped it off. Tour costume designer Adam Selman custom-made the look, and worked with jewelry designer Tom Binns to paint some of the 800 Swarovski crystals on the outfit.
