My husband also sings for his supper. He is a tenor and gets lots of engagements as a soloist. So not only does he wear dress shirts with cufflinks, he also wears waistcoats and bow ties. He is very posh indeed!
There is a very positive side to being married to a cufflinks-wearer. They appreciate new cufflinks for Christmas. Also bow ties and cummerbunds, and waistcoats, although I usually make those in secret.
Bow ties should also go on the list of accessories that end up in a tangle.
I bought him a beautiful box once with dividers to store all his cufflinks. Does he use it? Does he hell. They all go in together, mixed up in a plastic freezer carton. That looks really good on his dresser, I can tell you.
