Body type and Face Shape
Don’t go overboard with long necklaces if you’re shorter than 5’4” (162 cm). If you pick a chain longer than 16 to 20 inches (40 to 60 cm), it might overwhelm your small frame. If you’re short, you should also avoid big statement pieces. Just like the long chains, they can overpower the overall look and your outfit.
Again, those who fall into the average category are in luck, as they can wear almost any necklace length.
For those on the taller side of the spectrum, it’s best to choose long chains. While any length of the necklace will be flattering, long chains will accentuate the height the most. Furthermore, short necklaces may get lost in the overall appearance of a taller person.
The length should accentuate your best features
Wherever your necklace falls, that area will be highlighted. It will naturally draw the eye. That’s why you should avoid accessories that fall over areas you don’t want to accentuate.
For those with a smaller bust area, layered chain necklaces are a perfect choice. Ideally, they should be between 28 and 38 inches (71 and 96 cm) long.
If you have a fuller figure, it’s best to avoid long chains. They won’t fall properly. Aim for the length between 8 and 22 inches (45 and 55 cm). Those necklaces will rest a bit higher on your chest and look more natural.
Don’t forget the face shape
Just like the body shape, a necklace can accentuate your face as well. But, if you aren’t careful, it can draw attention to those features you’d rather play down. The best guide for choosing the right necklace length will be your basic face shape.
If you have a round face, you should steer clear of chokers and short chains. Those will only emphasize the roundness you probably want to minimize.
For those lucky ladies who have an oval-shaped face, the world is your oyster! You can choose any length of necklace you please.
For long faces, the opposite is the best choice – choose short chains. Anything between 16 and 18 inches (40 and 45 cm) will soften the appearance and give out the illusion of a shorter face.
Heart-shaped faces are ideal shapes for choker necklaces. In order to balance out the narrow chin and add fullness, choose a short chain.
