Trousers stress me out immensely. It took me years before I gave up worrying about whether my ass looked fat or my thighs chunked out, but do you think now I can relax? Now I have to worry about perfect pant length.
All sorts of people, with full-time jobs who cook and clean on a regular basis, also find time to hem their trousers to appropriate ground-skimming length. Because if the millimetre precision is off there'll be snickers.
While this seemed like a rigid world view, it got downright despotic when it dawned on me that shoes had to fall into hemline for ever more. I thought for a while that maybe I was overthinking it. But I wasn't. I was underthinking it. Clearly. Read the rules here.
Youlookfab.com tells us that "You need to commit to a length. You won’t be able to wear the same pair of pants with your ballet flats and your high heels. You’ll need to have an assortment of pant lengths if you have an assortment of heel heights." How do you know which your high heel pants will be when you buy them? How do you remember? Is there some closet coding I don't know about?
I don't know how people do it.
