Reference garment: (no reference to specific brand)
Original instruction by Injoo et al Pants sloper (p42) and "Short Pants" (p187).
Fabric: Woven. Cotton twill.
Not recorded: Almost all the steps recorded, you just need to change the fabric and color The only modification I made afterward is to "layer clone under" the welt pocket and open it. I also don't think this design need any buttons, topstitch and puckering texture.
.
Other thing you can do differently:
I recommend making the waistband curve/shaped, especially for women garment like this.
In the video, I lower the waistline by 3 cm. You can omit this if you want a high-waist silhouette
You can use single pleat instead double pleat. You can also experiment to use dart instead, or no pleat at all especially for less curvy avatar.
For the cuffed/turned hem, you can fold the hem instead. It gives a slightly more realistic result but not worth the hassle in my opinion, unless you want to use the pattern for real life sewing.
The type of pocket is up to you. If you add cargo pocket, it will become a cargo shorts.
