Channel your inner Carrie Bradshaw (or Hailey Bieber) and STACK THAT NECK. And yes, you can shower, swim and sweat in them. Never have to take them off quality. All of our necklaces are made of quality materials, (some sterling silver but most 14k-24k gold plated) meaning they are all water-resistant, hypoallergenic and tarnish resistant. Each necklace is designed to be stacked making them extremely versatile. Stack 4-6 of our necklaces for a more extreme look or 1-2 for a more simplistic vibe.
