Two strands of tennis brilliance running together — the Double Up turns one statement piece into a full layered look in a single clasp.
Reference where each chain length sits on most people. Between sizes? Size up — you can always layer a shorter chain on top.
| 16″ | Base of the neck — choker-adjacent. Great solo or layered on top of a longer chain. |
| 18″ | Just below the collarbone — our most popular, everyday length. |
Tip: Stack both lengths together for an effortless layered look.
Wipe gently after wear. Keep away from water, perfume, and lotion.
