Watches, rings, piercings, all are okay with me!
The one thing I can't stand is when men are dressed up and they have on a
bracelet. Usually they are gold links. I see them a lot on salesmen. They just make me think of pimps or sugar daddies- men that are trying to make a statement about their net worth. But that's just me, other people might think it's nice addition to your wardrobe.
