Marc By Marc Jacobs has revealed a new ad campaign for their Spring/Summer 2015. What's unique about these advertisements is that they feature models that were cast strictly through a social media campaign. All people needed to do was upload their picture onto Twitter or Instagram along with the hashtag #castmemarc to become eligible. They received over 100,000 entries but only eleven were chosen by a panel of the brand's designers and a casting agent. The result is a unique array of models from all over the world. Check out the photos and their stories below.
