When I wear jeans, sportcoat and a French cuff shirt I'll use silk knot links.What would you NOT wear cuff links with (besides the obvious jeans ?
Suit vs. SC another.
I think it depends... On a lot of things... For one, what KIND of cufflink? Danish modern? (Georg Jensen, Hans Hansen, etc.) Deco? (Guilloche) Whimsical?
Time of day is another consideration. Suit vs. SC another. For me, I'm headed towards a VERY streamlined cufflink collection. Primarily modernist, double-sided, primarily simple shapes. (That means I should have LOTS of pairs up for sale in classifieds shortly.)
Would you wear the to a job interview?
...for that matter I can hardly stand to see someone wearing a dress shirt without a jacket, regardless of cuff type.
