When we’re working out we want to know our gym kit has our back, enabling us to perform better, keeping us comfortable, and most importantly, looking good. It’s no surprise, then, that Adidas by Stella McCartney is one of our go-to brands for style-meets-substance sportswear. Collaborating since 2005, the sporty super-brand and British designer have revolutionised the offering of high-performance workout wear - they even designed the Team GB kits for the London 2012 Olympic & Paralympic Games. From beginners to amateurs and professionals, there’s a piece of kit for every ability, and even if working out isn’t your forte, the label’s ankle-grazing skinny leggings are just as cool in the city as they are in the studio. Busy-girls-on-the-go are sure to appreciate the appeal of something so versatile that it will see you from spinning class to brunch in ease.
