I was reminded of the late Duke of Windsor once again the other day. You see, at one point some years ago the online menswear fora were enamored of a trousermaker whose standard make included buttoning flys. Naturally, I acquired several pair, which I regularly regret every time I wear them (I leave the circumstances to your imaginations) .
It was the Duke of course who as one of his many clothing innovations popularized the zipper fly, a productivity enhancement that by now has saved billions of man-hours (I did not try to calculate it precisely but think about all those trouser wearing men saving a couple of minutes each day for the past fifty years). Like any apprenticeship business, tailoring tends to be a slow moving institution and without the Duke there is an excellent chance we might all still be fumbling with our trousers.
Unfortunately, the presence of buttonholes makes replacing the buttons with zippers one of those tasks (another is removing belt loops from trousers). It can be done but not well, and so I will be remembering the Duke for years to come.
Because he was right.
