Whether it's a partnership with a celebrity, a store or another designer, we've accepted that designer collaborations have become a permanent part of the fashion landscape. We've come to expect the usual high-low partnerships from the Targets and H&Ms of the world, so it's always refreshing when we can still manage to muster some excitement upon hearing about a new collaboration. Lucky for us, the coming months promise to bring lots of fresh excitement. From the much-anticipated Rihanna for River Island collection to Adidas for Opening Ceremony, these collaborations are sure to make some needed waves in the fashion world.
