Poppy didn’t go for a cape-centric look for Stella McCartney’s Green Carpet Challenge Collection unveiling at London Fashion Week. Instead, she chose to honor the designer by wearing this Resort 2015 striped dress featuring a contrasting bandeau and accessorized with a fun crossbody. This wasn’t the first time the linear dress made an appearance, though. Olivia rocked the striking creation in mid-June for the Third Person screening in New York City. Jacob & Co. earrings and orange Jerome C. Rousseau heels completed the look. Poppy’s side cut-outs exposed an extra dose of skin compared to Olivia’s slightly conservative take, so who showed their stripes best?
