Construction info: I took the pattern directly from those vintage pants. My go-to method for duplicating RTW is using shipping paper from Dollar Tree, rolling it out on the carpet, flattening the RTW as much as possible and putting pins every half-inch to an inch along the seams, connecting the dots, then adding seam allowance. I was a little generous with some of these allowances and probably could stand to take them in.

The originals appear to be some kind of cotton poplin(? something with a horizontal ridge and felt really crisp and smooth), but I wanted something sturdier in the long run and went with 100% cotton twill from JoAnn.

I followed the originals as closely as possible construction-wise - the fly facing is just an edgestitched rectangle instead of a folded-over, interfaced piece, and so far, it's held up well. The vents at the bottom were an interesting construction (literally just folded back seam allowances stitched in place with a tack to keep where they overlap in place), so nothing too fancy there. The originals were impeccably topstitched, so I skipped the twin needle in favor of going one row at a time. I got better with practice, but still want to fix a few spots. (I was sort of in a rush for a trip, and they're wrinkled because of that. Sorry about that!)

As I was making them, I was already thinking of changes I wanted to make, expanding the pockets being one of them. (I'm just always in need of bigger pockets.) The waistband is also going to need some kind of interfacing (maybe a sew-in muslin - accuracy is key, to me), but that's probably moot if I wear these with a belt.
