Stella McCartney's skill for marrying an effortless sense of femininity with innovative activewear is imbued into this crew-neck sweatshirt from her ongoing collaboration with Adidas. It's made from an organic cotton blend printed with a floral print in grey, pink and coral hues and is accented at the back with tonal zips for extra ventilation and freedom of movement. Temper the boxy silhouette with cropped leggings and low-top trainers.
