I started off 100% against pleats. Then I reluctantly got two suits (a Canali and a Ermenegildo Zegna) that had a small single pleat this last year, because I loved everything else about them. Now I am sold. I am a fit guy with a 32 waist and muscular thighs. I have always liked slim cut pants (I spend my time in the gym, I should be able to show it off), but I have always found that no mater what the tailor does there is always a little bit of a pulling issue because of my thighs, the pleat completely solves that. I have found them to be much more comfortable, and I do not have to worry when I get pants about them showing an un-businesslike bulge that most of the slimmer cut FF's tend to. I also have come to believe that a small single pleat does not really interrupt the clean look of FF pants so much as add a much needed bit of classy decoration. I still could not bring myself to big double pleats, but I have tried on a few pairs and will probably continue to give them a shot.
