You may not have had a tropical getaway this summer, but there are certainly ways to get you in the vacay state of mind. Take, for example, jewelry. A little bling can really make an outfit, and we've got our eyes on these Polynesian Cluster drops. The striking color scheme and marquise-shaped stones scream, "I've just spent a week on an exotic island," and the touch of rhinestones make for the perfect opportunity to glam up an ensemble. Less than $20, you say? We're in.
