Phat Pants Suspenders

I do not want to buy all the expensive braces rave of the internet, and they look easy to hell, someone knows how to do it?

Go to a craft store and buy some stretchy fabric

Fetching a pair of suspenders and take a regular pair of pants and experiment until you figure something?

uh, look. It is 4 strips of cloth around an O-Ring. It's hard to explain, easy to do. Just look at many samples of rave suspenders and you understand.
