What a difference a necklace extender makes. Each necklace has its own perfect resting spot and for each person and shirt and/or neckline, the perfect spot will be different.
First I put on this necklace with the original length provided by its chain.
But this results in a distracting shirt button plus the wonderful sterling silver feathers on the side were hidden under the collar.
By adding about 2″ with a necklace extender, I was able to drop the necklace into its ideal position.
