same thing here , i have tight pants too, but i want to sew in my old baggy ones
i was also thinking about stitching em tighter , maybe im gonna try it tomorrow!!
if you are going to do this youre going to loose any sort of insulation. be sure to do it with a shell pant.
flip the pant inside out
safety pin where you want the pant to come in
cut the excess
have really tight pants that scream "sewing guru"
