Object of Desire: adidas by Stella McCartney

Whether it's a walk through Saks Fifth Avenue or adidas, there's not much Stella McCartney can design that I wouldn't wear. I've always been a Lulu Lemon snob when it comes to my workout wear, but I definitely need some of these pieces. My favorites? Those bright blue running tights with loop detail at the calf, and that super comfy looking white tank (hello, Christmas list!). The super chic asymmetrical zip jackets are pretty awesome, too. Shop here.
