I, too, dislike low waisted trousers and lament at the quality of all clothes bought since about 2009. I still have well worn clothes from before that date, but almost everything bought since then lasts a year or two, maybe three at best. I’m not sure what changed, but something definitely did.

When I used to train properly and ate like a horse, I had a similar problem with the thighs. I’d buy the skinny / super skinny fit, but buy them 2-4" bigger at the waist and wear a belt. Seemed to solve the problem and nobody ever said they looked silly. They’d be the right level of looseness all the way down. Maybe an inch or two extra material down the whole length, but they still hug the leg, rather than flaring out (I don’t like them wide at the bottom).

As for the crotch length. I’ve noticed, too. And pockets are becoming so small as to be useless – during the era when mobile phones are getting bigger and bigger. I can’t even get my hand in some pockets, never mind a wallet or phone. In fact, it’s the first thing I check when I pick up any style of trousers: will I lose my keys because the pockets are too small? If the answer is yes, I don’t even bother trying them on.

Edit: thank you for setting up the opportunity to rant about trousers. I’m glad I’m not the only one noticing similar changes.
