Do you (or anyone else) have a picture of this? I find it hard to believe, I want to see it in order to believe it. Won't the sleeve be too long once you button up the cuff, the extra sleeve material will pile up the arm right?
Manton writes in The Suit that a little bunching is considered by some to be aesthetically desirable. (And that if you don't give the sleeves some extra length, it's very difficult to tailor a shirt so perfectly that the sleeves don't ride up.)
The English convention seems to be to show about half an inch of shirt sleeve below jacket, which I think works well.
Surely much better for sleeves to be a bit too long rather than too short?
I always wear double cuff shirts and have the cuffs well-starched and ironed into the folded back position. I think this tends to give a better shape.
There is no single standard for fit, despite what all those "guides to dressing well" would have you believe. Italians typically wear their cuffs snug-- so much so that some put the watch over the cuff. By the same token, there are a lot of very well dressed men whose cuffs are rather loose. I wear a substantial chronograph at least once a week, and it requires a largeish cuff opening.
You'll get a lot more enjoyment out of dressing once you recognize that no too garments fit precisely alike, and that the rules should really be seen as general statements, not laws of the land.
