Listed below are some common necklace lengths and their names:
Collar - 30/33cm
Collars are usually made up of three or more strands and lie snugly on the middle of the neck. Very Victorian and luxurious, collars go best with elegant v-neck, boat-neck or off the shoulder fashions.
Choker - 35.5/40.5cm
A choker is perhaps the most classic and yet versatile of all the single strand lengths. A simple choker can go with virtually any outfit from casual to fancy evening wear, and just about any neckline imaginable.
Princess - 43/48cm
The princess length necklace is best suited for crew and high necklines. It also complements low plunging necklines.
It is the perfect length to support a pendant.
Matinee - 51/61cm
Longer than the choker, and just a bit shorter than an opera length, the matinee necklace is the right choice for casual or business dressing.
Opera - 71/86.5cm
The opera necklace is the queen of all the lengths. When worn as a single strand, it is refined and perfect for high necklines. When doubled upon itself, it serves as a versatile two strand choker.
Rope or Lariat - 114cm (at least)
Dripping with elegance and sensuously sexy, the pearl rope was a favourite of Coco Chanel.
For those looking for the complete wardrobe, this length is a must.
Lariats are at least 125cm long, with the ends left unattached for knotting or wrapping around the neck.
