I wasn't sold on summer's new eyewear trend - mirrored sunglasses - until I saw a few of my favorite fashion bloggers working the look at Coachella (via Instagram, naturally). These reflective sunnies add a dash of fun and an aire of mystery at the same time. All while adding major attitude (and a little sun protection, too). Here, five pairs under $50 to help you test the trend (then invest in a pricier pair if you love it - I'm all for quality eyewear).
