There is one item that everyone (and we aren't being hyperbolic here) is wearing this fashion month, and no, it isn't the Gucci logo T-shirt or the Simon Miller Bonsai bag, but a personalised iPhone case. Alexa Chung, Kendall Jenner, Cara Delevingne, Beyoncé, Lily Donaldson, Natalie Massanet, Hailey Baldwin, Jourdan Dunn, Taylor Hill and many more (seriously, we could go on and on) have the exact same iPhone case.
