Serotonin Necklace
Necklace Size Guide
Choose your length on the product page. Most of our necklaces come in 14" to 22", with an extender chain for a little extra adjustment.
-
14" (35cm) – choker
Sits close around the base of the neck. -
16" (40cm) – collarbone
Falls just below the collarbone. Ideal for small pendants and initials. -
18" (45cm) – our most popular
Rests on the upper chest. The safest choice for a gift. -
20" (50cm) – relaxed
Sits a little lower, and is lovely for layering. -
22" (56cm) – longer
Mid-chest, for layering or a longer look.
In-between lengths (15", 17", 19" and 21") are available too. Most necklaces come with a 1" (2.5cm) extender, and some with 2" (5cm) – the product details say which.
How to measure: put a piece of string around your neck where you'd like the necklace to sit, then measure it flat.
Layering tip: choose lengths about 2" apart so each necklace sits on its own.
