Still wearing that Tiffany heart pendant from your sweet sixteen? It’s time to up your accessories game. Start with a piece from Double K, a collection of necklaces and earrings made from vintage chains and recycled brass pendants. Designer Kelleigh Kincaid scours flea markets and eBay for charms, lockets, and semiprecious stones and casts her own brass pendants. Then she juxtaposes the sweet (gems) and the not-so (oxidized silver pieces), pulling everything together with chains from the ’70s and ’80s. The dark, sexy baubles are meant to be layered, so don’t be afraid to throw both the Turning Leaf (vintage leaf charms, recycled brass pendant) and the Chandelier Affair (vintage chandelier crystal, aquamarine, quartz) around your neck. Get one while you can. Or Elsa. Available at Grasshopper 510, 1944 North Damen Avenue, at Homer Street (773-292-0510 or grasshopper510.com). To see styles, go to doublekjewelry.com.
