We already know what adidas by Stella McCartney has in store for Caroline Wozniacki for the next year. They presented their spring/summer 2011 collection during the London Fashion Week.
Wozniacki showcased the new clothes playing a 3D tennis videogame. As you can see Stella is sticking to neutral colors for tennis, which are practically the same as those of Wozniacki's US Open 2010 dress, just that the touches of bright colors switched from lime to pink.
The above dress looks more unique and new than the one Wozniacki is wearing, although both are nice. I like this negligee-inspired look. (source: Tennis Served Fresh)
