I'm so glad to be 5'9".
Having said that, and being a guy who is 6'3" from the waist up and 5'1" from the waist down...jackets and french cuffs do accentuate my torso/leg disparity.
That's about as metro as I get- Dom rules!- but my gut reaction to french cuffs is that there is a place for them. At work, if I encounter a sales rep who is wearing them it just sends up a red flag. But if I meet a lawyer or an executive who is wearing them I am probably more impressed by it.
Socially, I would not expect to see them anywhere I hang out, but I'll leave the judging on that front to the folks who actually have social lives. And my look is probably more quasi-professorial, anyway, which requires frayed cuffs, elbow patches and sensible shoes, and which I have done for so long that a suit makes be feel uncomfortable. Nearly always a sport jacket and plain front pants (another short leg thing, vaticanplum can explain I'll bet) for me.
This is a great thread, but could someone please point me to the farting video? I haven't kept up...
