This is the new Spring collection that Stella McCartney did for Adidas. Stella is collaborating with everyone this years, including Target and H&M. For Adidas I think her style is mostly influenced by ballet, dance, tennis, and yoga. Her stuff is definitely really cute and even functional outside of the gym. I would totally rock most of those jackets with some tight jeans, black boots, and a chain. And the tennis dresses are super cute, it makes me want to pick up tennis again once the weather is warmer. But her stuff is not cheap. Her jackets range from $150 -$250. The teal running jacket that I really like is $210.
