If you think about famous sisters in the fashion system, the first pair that comes to mind are Gigi and Bella Hadid. But they are not the only siblings sharing the catwalk! Not only: some of them are even twins 🙂 What could be better than working with someone who knows you so well? It makes for perfect harmony, so much so that designers, like Balmain — who chose Joan and Erika Smalls for last winter’s campaign, as well as the most important magazines, like Vogue — that featured sisters Lily and Ruby Aldridge in May 2013 — are more and more interested in beauties that share DNA.
