Colorful beaded necklaces aren't just accessories this summer--they're the main event. Wear them solo or layered with sunlit, unabashed confidence--with everything. Yes, even a swimsuit. I'm going to show up in these bold beauties from Anni Lu, above, Elizabeth Cole (never taking this off!), Dries Van Noten (I mean, wow!), Brinker & Eliza (only one left!), Madewell (also this), Chan Luu, Mango (last pic), Oiya, and Adina Reyter.
