Forget the twinning emoji you just texted to your BFF — those gals are wearing bodysuits. For Ciara and Gwen Stefani [1], it's all about the sexy, sheer gowns. The pair posed backstage at the Billboard Music Awards [2], showing off their embellished designs and, yes, a peek at what was underneath. Maybe it was because of Gwen's giddy smile [3] or the silver shine of their looks, but this matchy-matchy moment is bound to stick with us until tomorrow. Just read on for a glimpse at two of the most stunning body-hugging looks from the evening.
