Get a small pair (for cheap only) and deconstruct and add/subtract where needed. Yes, you can add with these pants; the inseam variance is more than 26mm in the3 legs.. and there's plenty to play with. The biggest difference the swede variety have over other wool pants, is:
1. they have a tapered gussett on the crotch inseam (as if these pants needed more room to roam
)
2. they are grey in color.. moreso than the typical olive drab of all the other woolen pants.
3. They have the leather gaiter straps at the bottoms (as an option). Nice if you don't plan on carrying an extra set of snow blockers.
4. Metal (tin?) buttons. Need there more be said?
5. Side thigh pockets were later added . Often they were in a different dye lot, and somewhat more "purple"? in color (late 50's?).
I've got 3 pairs @ 34"x34" inseam/waist.. the reference to bagginess is more of an evolutionary style dysfunction rather than the cut on the pants. Back in the 40's-50's men wore their pants much higher than currently. Suspenders were the norm and wearing pants lines at the top of the hips (yes, with the waistline being at the top of the ilium) were all the design.
These pants stretch/move much better than their German and US counterparts. It;s a shame you can;t get them closer to home in a normal size. i would be willing to trade 32-34 inseam swedes for AaBe Dutch blankets (nearly non-exestent wool tweeds over here
) They are going for 30$US while the dutchie dekens are hitting 25-35$ and a constant 30$ isle side.
hmmm
I think I'd check the label these days, best be sure before someone goes up in flames
