This is the era of ever-shrinking men’s trousers — they are tailored and shorter, tighter and shrunken, too tight and too short. And even occasionally veering into: Pitbull, exactly how are you breathing in those high-­waisted white pants?

The look of menswear changes at a snail’s pace, and sometimes it takes years before a not-at-all outlandish idea trickles from the runways, which are now hosting the spring 2015 collections, to the mass market. But when a fashion idea finally reaches the vast middle ground, it tends to stay a while, putting down roots in the menswear landscape.

Thus we are deep in fashion’s equivalent of an old-growth forest — surrounded by men in aggressively tailored pants.
