Most of our necklaces are adjustable. We typically use a standard (princess) length of 45cm (18"), with an additional 10cm extender chain, which allows adjustment up to matinee length (55cm / 22"). These are the most popular and versatile necklace lengths.
Some of our designs have different lengths, and a few are non-adjustable. Be sure to check the product details and sizes & materials section for the specific measurements of this necklace.
Use our necklace length chart to see where different lengths will sit on the body. However, everyone is different, so we recommend measuring an existing necklace or using a piece of string to find your ideal fit.

Important: Necklace lengths refer to the total circumference. If the necklace features a pendant, it will sit lower than the chain length alone—check the sizes & materials section for full sizing details.
