Sorry if I am unnecessarily bumping this thread - but I feel it's an important point to emphasize -

Shirts with French cuffs that are not fitted shirts tend to look really bad on the wearer, unless the casual fit shirt happens to be a very good fit. The key is in the sleeves, where a lame sort of billowing can occur.

I've noticed in NY (where I worked in investment banks) that french cuffs sans suit / tie were way more popular than in SF (where I worked in VC). However, despite the higher prevalence in NY, the acceptance rate in SF was just as high.

I'm in LA now, wearing a french cuff shirt (Pink) without a tie, and slacks - co-workers are indifferent to positive on it, no negative.

I have, never, ever seen someone where french cuffs with jeans. Wearing Pumas with a blazer is a good analogy for the look I think this achieves.
