On most guys, this could improve their gait since their knees could go higher with each step.
And the twirls would be magical.
I do not agree!
All depends on the human figure.
Any options pants are good if they are suitable for you. And the one fold, and with two folds and no folds.
It's very Idividualny.
I tried different versions of bespoke trousers.
And for me the most suitable shape - it wrinkle-free.
Last 50-60 pairs of pants, I ordered a bespoke only without the folds.
In my sport legs, narrow waist, the folds are not relevant. It is a pity of course. After all, they are the correct and classical. But to me they fit much worse than those without wrinkles.
So for me the most appropriate - pants without pleats.
And this is not a whim, but simply a selection of my figure.
However, I agree with you that most people are better suited bespoke trousers with pleats than pants without pleats.
I just, alas - of the minority.
