TheScandal actress chose an indigo patterned Giles Deacon design, while our current style crush opted for a fuchsia Dsquared number. Witherspoon, meanwhile, wore Dior's embroidered mini to her Nashville premiere.

Over in Paris, fellow Dior devotee Olivia Palermo was in attendance for the fashion house's spring show. She added excitement to her black coat dress with colorful accessories and modern shades. Back in the States, Jessica Simpson showed off her street style in Alexander McQueen's mixed plaids.
