Article is dumb, but many of the comments are quite good. So good they offer better advice than most of the internet men's clothing message boards, er fora.
Between Princes Harry, William, and Charles, pretty much the whole sartorial range is covered, from low, middle, to high. They each do their respective things with panache, so i don't see the problem.
I loved the response, "He looks like a GUY. He doesn't look like a FOP." That same respondent complained that too many men were preoccupied with their grooming and clothes and looked like a bunch of "closet homos."
At least in my part of the country, when I am out and about, the only man I see preoccupied with grooming and clothes is when I see my reflection in a shop window!
In defense of HRH, he may have been trying to be as inconspicuous as possible to make his way through the airport without being pestered.
Men, and women, for that matter, who dress sloppily often smell, too.
