When you say you sized down and altered waist, did you have them let out? How are the one pleat trousers sized in the waist? Basically, I have found a sale pair but are a size down or a second hand pair that are a little cheaper but the size up. I can't seem to find a 46 in a decent price anywhere. Just trying to work out what would be better, size up or size down. Does anybody have a pair of one pleat trousers and can comment on fit?
