I've been meaning to make reproduction vintage pants all summer, and it finally happened. I'm tremendously pleased with how they turned out. I used Simplicity 3688, which is a reprint of a 1940s pattern, with relatively little modification. They're very easy to wear, as well, which was my main goal, and the pockets I added turned out well.
You can't really tell from these photos, but the fabric is denim and has a thin stripe (blue/navy). Excuse my headlessness. These were a pain to take, and I couldn't get the exposure right on any of the ones where I had a head.
