I've always wondered how it came to be that the English close their shirt cuffs with cufflinks while the Italians and most of the Americans use buttons.
Curiosity aside, I like the informality of buttons with odd jackets and weekend suits and the dressed-up look of cufflinks with a city suit. The only knock on links is that they cost more than shirt buttons, but that shouldn't be too much of an obstacle. One good pair is all that's required for every day wear. After all, no-one notices if we wear white plastic buttons on our shirt cuffs every day.
If a man has but one pair, I think it should be gold and double-sided, with the two sides joined by a small chain. I've seen antique 14kt machine-turned versions on eBay for about $100 a pair. Of course, when money is no object, a pair that's hand engraved with your initials and family crest, like the links from the English jeweler Armour Winston in the photo, can be had for a considerably larger sum.
Another reason some men have avoided double-sided links is because they are perceived as more dificult to don than either buttons or the modern type of single sided link with a swivel on the other side. That's not true, of course. Links go into the cuffs before a man dons his shirt. The opening of a linked cuff is just large enough for a hand. Nothing could be simpler.
