Celebrities are pairing their red dresses with an unexpected nail polish color—blue! Busy Philipps updated her French manicure with cobalt tips when she wore a floral Hawaiian frock, Eva Longoria opted for a steely metallic navy to pair with her Alberta Ferretti halter, and Emma Stone lacquered on a pale dusty blue when she wore embroidered Lanvin. This is also a look Beyonce tried—she wore a punchy azure manicure with a red Temperley dress for her first appearance since delivering daughter Blue Ivy in February.
