A necklace looks good on both men and women but it is ideal for men since the chains are more masculine looking than chains worn by women. Leaving your favorite necklace in an unclothed state (on its own) will make you look tired or drunk if you're wearing this accessory that most are used to seeing. You can wear them during the day and evening, if you are going out or attending a party in which chain necklace will be noticed all over the place.
