I used to be a fan of the bracelet stack, now I think it's overdone. I never really wear that much jewelry at all, and I especially never changed up what I wear from day to day. A couple of years ago I made it my goal to wear something different than pearl studs every day, which brought me to my crazy obsession with hoop earrings. So, now I'm trying to break into wearing necklaces. Specifically necklaces plural.
I like to layer two to three necklaces, with varying lengths, colors and styles. BaubleBar, Shop Bop, and local boutiques are great for finding options.
