Denim looks really nice. Never seen anything like it. With mass-production the short fly is easier and they end up with less second-$. For the male autonomy it's really not practical. People are used of the cheap look (they can have it). So the thought, "old fashioned", doesn't apply from my perspective. Like the thread work on the hip pockets. But the pockets themselves are too squareist for my taste. Angles and/or curves makes them more exciting. The yoke seems to dip to far down in center back. It depends on how flat or round the seat is. Flat is less distance to cover and less angle into the small of the back. The purpose of a yoke there is to add shape. This is done by adjusting size and curving the lines however much is best. See where the prominent sag is at and draw the curve accordingly. A slight curve up. You can experiment with a down curve and see how that works. The silk twist button holes I made deteriorate, if they go into the wash. How I use, regular modern day sewing thread doubled, but not twisted. To make it look nice and neat the two threads are side by side, even in the knots. For the gimp, same thread doubled, side by side (so really no gimp at all). The front pockets dip down too low at the sideseams. The iron work is worth it. How you did the insides is really nice. Glad you posted this project.
