RiRi started the show in an electric blue robe to sing "Only Girl (In the World)," but it didn't stay on too long, as she quickly took it off to reveal a studded neon bikini.

According to Rolling Stone, her concert had 6 costume changes over 24 songs, including a "white bondage corset" with handcuffs.
