CHOKER: 14 - 16 inches ( 35 - 40 cm )
Worn close to the neck and against the base of the throat. This length necklace fits snugly around the neck. It emphasizes the neck, shoulders, and collarbone and highlights the face. It is flattering with almost any neckline, especially off-the-shoulder and boat neck.
PRINCESS: 17 - 19 inches ( 43 - 48 cm )
Worn on the collarbone and at the top of the bust line. The princess length necklace is popular because of its versatility. Often worn with plunging necklines, it also goes well with V-necks.
MATINEE: 20 - 24 inches ( 50 - 60 cm )
Worn between the collarbone and the bust. The matinee is the preferred length to complement business attire. The length is not restrictive, so it looks just as nice with jeans as it does with a suit.
OPERA: 28 - 34 inches ( 71 - 86 cm )
Worn below the bust line or as a double strand. The opera length can be worn as a dangling single strand or, when doubled, a draping two-strand choker. It elongates the torso.
LARIAT: 38 - 40 inches ( 96- 100 cm )
Worn wrapped and then draped. The lariat or rope-length necklace is worn looped around the neck several times, creating the illusion of a jeweled scarf. The ends of a lariat are not attached.
SIZE RANGE: 5 – 10 inches (12.7 – 25.4 cm)
MOST COMMON: 7 inches (17.8 cm)
AVERAGE: 6.5 – 8 inches (16.5 – 20.3 cm)
Wrap a flexible tape measure around your wrist, just below the wrist bone. Depending on where you intend to wear your bracelet, add ½ inch (1.3 cm) to 1 inch (2.5cm) to your wrist circumference. Then, find the closest bracelet size. Elastic, or stretch bracelets, are typically advertised as "one size fits all" but are usually 7 inches.
