Last night at the 2012 Teen Choice Awards, one of our favorite rock chicks, Gwen Stefani, performed with her band, No Doubt. While on the red carpet she opted for an all-black leather look, on stage Gwen wore a more eclectic ensemble. What we loved the most were her black-and-white beaded bangles, which she stacked on top of one another for a dramatic effect. If you want to get the arm party started like Gwen, get a few of these UO beaded bangles ($7, originally $24) and stack them on top of one another. You can wear them with an artsy black and white look like Gwen's, or they would also look amazing against an all-black or all-white ensemble.
