A few years back I bought some summerpants that fit me well enough to go camping in them.
These days they don't fit me anymore... so I made them smaller! I also made them shorter.
At first I removed all the extra's and almost the entire the waistband.
I took one of my well fitting pants and that helped me getting it into shape. I also used the pin method, you wear it inside out and pin where you need to loose some fabric.
After I was satisfied with the result I sewed the waistband back on and shortened the legs.
Now I was to late with refashioning to actually wear it on my campingtrip of this year. But I will certainly wear it next summer!
