From Black Snail Patterns:
This is a sewing pattern for trousers worn from 1830 to 1860. The sewing pattern contains two different versions, one with a wide leg and comfortable fit for daywear, the other tight fitting for evening wear. Both have a buttoned fly front.
This sewing pattern tries to show a detailed and historically accurate construction. But of course a modern working and machine sewing can be chosen.
This sewing pattern perfectly fits with:

The pattern comes with detailed and illustrated sewing instructions in English and German. An additional tutorial for the pockets is available on my blog.
