I blame the Wetherly Fashion Group for my latest must-have: Lana Jewelry’s large Cascade earrings in 14k yellow gold. These were on display in the Manhattan-based showroom last week during a market preview of new jewels, and now I’ve got all things disco on the brain: Bee Gees, Saturday Night Fever, and even Olivia Newton John circa Xanadu. Think old-school roller skates, crystal-studded cornrows, and a pair of these shimmery, beaded curtain-esque earrings and you, too, will be ready to tap into your own ’70s funk persona.

Large Cascade earrings in 14k yellow gold are four inches long; $1,720; Lana Jewelry
