Olivia Wilde looked amazing (as usual) at the Independent Spirit Awards. Her bohemian glamour look was completed by her maxi dress, shiney hair, and gold jewelry.  The layered necklace look that she wore is easy to replicate. The best thing is to keep the necklaces thin and of varying lenghts, then add one piece to be the standout (like a pendant).  Banana Republic has a great selection of costume jewelry and many of these pieces can be worn together, just like Olivia.
