After launching in February, the #mycalvins social media campaign has enlisted a number of notable names in fashion for Instagram posts featuring the waistband of Calvin Klein underwear. Models such as Miranda Kerr, Lara Stone (who previously fronted print campaigns for the label) and Poppy Delevingne are part of the campaign as well as musicians Fergie and Iggy Azalea. The brand has also tapped well-known fashion bloggers such as Chiara Ferragni of The Blonde Salad and Rumi Neely of Fashion Toast for the project. See our roundup of some of the #mycalvin images below.
