Is a 20-inch necklace too short?

Whether a 20-inch necklace is too short largely depends on what you wear it with. Generally, a necklace should hit above or below a neckline for a balanced look. Also called a matinee necklace, a 20-inch necklace usually hangs just below the collarbone, making it ideal for coordinating with many tops and dresses with lower necklines.
