This idea has come at the right time in my life, since I usually climb and lose weight as if my body were a roller coaster, and that's why I have to modify my pants and sometimes I even lose them because I do not have any left. It made me laugh your comment that you prefer to think that the pants have shrunk, I also do that, I tell my mother that my clothes have shrunk. From now on, I will use the technique he has explained to enlarge the pants, so I kept his publication to guide me when I tried. Thank you very much for sharing your knowledge, it will be very helpful.
