If there’s one trend to try this season, cobalt blue is it! The vibrant color can give an outfit instant cool and make for a bold statement like Kim Kardashian’scurve-hugging gown. The popping hue is being splashed on just about every fashion item you can think of. Take a baby step with cobalt by trying it on your nails (we love “Baker Street” by Nails Inc., which Beyoncé wore after having baby Blue Ivy). And don’t forget about cobalt-colored jeans!
