Another option is Aero's CC41 trousers. Those are simply gorgeous - the tweeds might be too heavy for you, but the cotton drills will be superb. Made to a CC41 wartime pattern, but - copying the original pair they used for patterning - they have cuffs. (Cuffs were theoretically banned in Britain in wartime in order to save cloth, but it was not unknown for a compliant tailor to be persuaded to put an incorrect inside leg measurement on paper so that there was enough cloth in the trews to create a cuff.)
Aaaah, forgot about those! So you mean... Let's say I order a pair in 34 length (which is the longest they offer), I'd be able to undo the cuffs and add one inch or two to the inseam?
