I think the length issue is real for jeans and trousers because they aren’t consistent, and the lengths have increased. I’m 5’6” and a 31” inside leg which I’d say is a pretty standard size, and have always had regular length which fitted without alteration. Last week I bought a pair of chinos, and for the first time ever, I needed short length. It’s a pain as you have to get dressed, go out and get them and try them on. I’d only bought some jeans in regular a few weeks ago which were fine. It would be better if they actually stated what length the inside leg is, rather than just stating long, regular and short.
