Pearl necklaces that are choker length refers to necklaces that are about 14 to 16 inches in length and fit loosely around the neck, just above the collar bone.  They may be a single strand of pearls or they may be multiple strands.  The photo shows a 100 inch strand wrapped seven times around the neck to produce a beautiful multi-strand pearl choker.  This style looks great with a strapless dress.  A single strand choker length pearl necklace can be worn inside the neckline of  a tailored shirt, a little black dress or a cool summer outfit.

A slightly longer necklace is considered the standard length for a pearl necklace.  It's 18 inches long and called princess length.  Matinee length necklaces can be between 20 and 24 inches in length and pearl ropes can be anywhere between 36 inches and 120 inches.  Many of this year's necklace styles are on the longer side, but the pearl necklace choker length will always have a place because it draws the eyes towards the face.
