You know the hackneyed fashion myth: Under no conditions should black and navy blue ever be paired. We've got news for you: That once-unbreakable rule has been shattered to shards recently, as the two colors have been spotted being worn together on the runway, in the front row, and definitely in the streets.

The combo first started making waves during the Fall 2012 collections, as scores of designers including Carolina Herrera, Miu Miu, Gucci, Prabal Gurung and Céline sent looks that incorporated black and navy down the runway, while style influencers like Alexa Chung, Mary-Kate and Ashley Olsen, and Kate Bosworth were quick to jump on the trend, proving just how cool the pairing can be.

The good news: Even if it's only adding a pair of opaque black tights to a dark blue dress, pairing black and blue is beyond simple using stuff you already have in your closet.

Read on to get a glimpse to see who's wearing the chic color combination, and get a dose of inspiration from the runway and your favorite It girls!
