Love the jewelry Serena and Blair have been wearing on Gossip Girl this season? It’s most likely from this high-end accessories shop in Lincoln Park (New York, Rhode Island and Palm Beach, Florida, also have outposts). Sequin designs and manufactures upscale costume jewelry under its own eponymous line, as well as for label Badgely Mischka. You’ll also find goods from designers such as Ralph Lauren, J Mendel and Kaufman Franco in the store. And even though the designs are luxe, the price range (starting at $22, and going up to $1,000) isn’t that intimidating.
