Here are some general guidelines to follow when choosing the length of a necklace. For a bolder look suited to those with a more daring fashion sense, go with a shorter length necklace. Medium-sized chains, on the other hand, are a great match for people that prefer to go for classic and traditional styles, whereas casual, laid back personalities usually go for longer necklaces that make a perfect complement to boho, hippie styles.
If you're looking for a necklace to wear on an everyday basis that is able to suit any occasion, opt for a mid-size necklace, as you can never go wrong with it. When you stick to a rather classic look, that's when you know that you'll always get it right. With mid-size necklaces, you can step up your game instantly, keeping it classy yet without being too over the top if you accessorize with a perfect pendant.
