I have made this pattern for elastic-waisted pants with loose, flowing legs in a drapey linen-rayon blend. They are intended for summer wear.
The pattern's instructions are amateurish, and I could not make sense of the instructions for making the fly. Eventually I realized that the pants could be pulled on without a zip fastening, so I omitted the fly and finished them as simple elasticized pants with two side-seam pockets.
After measuring the inside leg I added about 2cm to the length. I should also have increased the rise as it is not quite enough, although the pants are wearable.
