It is quite easy to overdo it with bracelets as they are small and it can be tempting to wear multiple at once. One of the things you should pay attention to when wearing a bracelet is the wristwatch you will wear that day. After all, your hands are a pair, so they will be seen in conjunction with each other, including the accessories on them (this may sound obvious but people often forget!).
Rope or leather bracelets are usually best matched with casual and business casual wear. Wearing a combination of 2 or 3 of these more comfortable bracelets is the easy way to go, assuming the choice of color is harmonious. Metal bracelets fall on the more formal end of the spectrum. Wear one at a time and match it with your watch and other metal accessories you may be wearing.
