Want to make a statement this spring and summer? These mixed media necklaces will rope you in and make you stand out. They’re global and artsy. Can you picture one of these with a white tee? I surely want the J.Crew rope cord necklace (#5), but the Topshop monochrome rope collar (#1) has my name all over it too, and it’s a fraction of the J.Crew cost. Which one’s your style?
