Back to the minutiae:
Who wears them? Do you go forward/reverse, double or single?
Are there any "rules" for pleats i.e. only with belt loops, or only without belt loops & with bracers etc.?
I have ordered some casual cotton/linen pants with single reverse pleats (I know forward is more trad, but it just doesn't look as good to my eye) and belt loops.
I'm considering adding pleats to the second pair of trousers I'll order for my PJ suit with adjusters and internal buttons for bracers (the other pair has belt loops and no pleats - so I think it will be a nice way to differentiate the two).
Most of my trousers both casual and business are pleated.
I favour double reverse I find they drape better with my physique and I have always preferred them to flat fronts, especially now being a desk jockey. I get mine mainly from the US Bills Khakis M2P and BB Madison 1818 are my preferred OTR business trousers.
(about to veer off topic)The LE Linen/Cotton trousers I just bought are a tight fitting 38 this is the quandary for me at present. I know I have been carrying too much weight and finally the quacks have sorted it out and with extensive gym time in the past month I have gone from a 46 inch chest down to 43 similar is happening with my waist line form 40 to 38. So until my body decides it has shed the excess weight I will not be buying any trousers.
That said I would if ordering a winter weight suit go for a double reverse pleat with internal buttons for braces, never been a fan of size adjusters the look of them is just too Mod for my tastes.
