I am not sure I have ever had such a disagreement with the excellent Easy and Elegant Life, but there is always a first time. Perhaps it is the small snowmageddon that is playing tricks on me and luring me into a false disagreement. But, seriously, for GQ this is not a proper choice, and for reasons E&L partly notes in his post.
I think the crux is his claim that style and elegance can exist apart from each other. I am not so sure. Style is timeless; we ban the word fashion here. But elegance is a way, or manner of style.
Take the pics that E&L uses in his post I linked (above). Cary Grant and the Duke of Windsor are truly both elegant and stylish. There is a sense of timelessness to each of their dress (and I would put the Duke near the Dandy end of elegance and style).
I think the Duke is certainly sophisticated as a dresser, but he is also elegant. Sure, the stripes and panels look a bit loud to us. The manner he carries off the entire ensemble though is quite elegant. The only odd thing is the way he wears the tie. I would love to hear from people as to the apparent shortness of the tie with the tail obviously visible. It does seem a bit odd, but I am sure I am missing something.
Dandyism, however, mentions elegance as a part of the Dandy look. Note Tom Wolfe:
Why is the Duke (or Wolfe) more Dandy? Perhaps the Kinks will help:
At any rate, I like E&L quite a bit, but I think we disagree on Depp, style, and elegance.
