I enjoy seeing men wearing jewelry. Not too much, not too gaudy, but something that sets an individual apart from everyone else. An interesting wedding band, as opposed to a standard, commercial one; a great lapel pin is like wearing a miniature piece of art; a bracelet that has some presence on a wrist, yet is understated.
Mostly, though, I adore cufflinks. These can be very expressive pieces of art and reflect one’s personality- humorous and fun. No need for a tuxedo, just a casual shirt with French cuffs and a pair of jeans!
