Stella McCartney Spring 2015–While last season was a story of comfy knits and fringe, for her spring-summer 2015 collection, Stella McCartney channeled the seventies with a feeling of languid ease. From a white utilitarian jumpsuit as the opening look to denim top and skirt combos with whimsical zig-zags, it was all about daytime luxe for the Stella McCartney woman this season. Of course, girl of the moment Cara Delevingne made an appearance wearing a dramatic cape and mini dress look. The finale featured lightweight dresses with a mix and match of kitschy prints floating in airy layers.
