Hard as it is to believe, beauties Poppy Delevingne, Karlie Kloss, and Caroline Issa have loved and lost — those losses, however, were all of the fashion variety. In a new video series from Moda Operandi and St. Regis Hotels & Resorts titled "The One That Got Away," Poppy, Karlie, and Caroline join Leandra Medine, Anna Dello Russo, and Giovanna Battaglia to talk love at first sight and lament their biggest designer regrets. So, what clothing keeps this set up at night? For Poppy, it's a celestial Chanel Resort 2012 gown, for Leandra, a peplum dress made her decide between purchasing and paying rent. And for lucky Anna, "It doesn't happen to me. Never. I missed so many boyfriends but not outfits." Scroll through their romantic stories as you imagine your one that got away.
