People Editorial Guidelines Published on July 15, 2015 09:31 PM Share Tweet Pin Email Off-the-shoulder pieces are a huge trend this season. And one dress in particular is showing up all the time on some of our favorite style setters — Reformation’s “Mariana” frock. Getty; FillMagic; Rex Shutterstock Getty; FillMagic; Rex Shutterstock So far, Minka Kelly, Jamie Chung, Jenna Coleman, Sophia Bush, Vanessa Hudgens and Emily Ratajkowski have all worn the design, which unfortunately, because of it’s celebrity popularity, is sold out in most colors. (It’s also the best Fashion Faceoff of the summer!) So what’s the hype? The dress looks cute with any kind of summer shoe — wedges, espadrilles, flats, metallic slides. It’s also made from deadstock materials (fabric that has been over-ordered and would otherwise go to waste), so you can feel good about wearing it. Plus, it’s perfect to pack in your suitcase for a summer vacation. Bush brought hers on a trip to Uganda where she met the artisans behind brands Akola Project, 31 Bits and Sseko Designs, while Ratajkowski wore hers in Positano, Italy recently!
