I prefer to wear non-pleated pants for both suit pants and regular dress pants. I don't mind the one pleat because it adds a nice shape to the pants but pleats are just not for me. I think they're outdated but then again it depends on who you are, I'm in my mid 20's and feel out of style with 2-pleat pants. Pleats, A.F.A.I. have read, allowed the pant to expand when men wore their pants at their natural waists. Since most of us young-ones wear our pants on our hips, this functionality is negated. :. if you wear your pants at your waist and are not Don Draper, pleats might help. But if you wear them at your hips, they're kind of a waste (ha!) no?
