Who wore what this weekend: Kerry Washington dazzles in floral Erdem

Red carpets were abuzz with stars this weekend -- attending the Academy of Country Music Awards in Las Vegas, the iHeartRadio Awards in Los Angeles and the Olivier Awards in London. Needless to say with the variety of events, the looks that walked the red carpet were equally different from one to the next!

Kerry Washington attended a dinner in her honor to celebrate her April ELLE cover, dazzling us with a floral Erdem dress that shouted spring. Some of our favorite British actresses -- from Game of Thrones's Rose Leslie to Downton Abbey's Laura Carmichael -- looked resplendent on the Olivier red carpet, while country music stars Miranda Lambert and Carrie Underwood brought out their sultry side at the ACMs.
