I tried this money belt on when it arrived.  I had to make it as large as possible in order to fit my waist.  It has this sort of clip to keep it on.  I was afraid that I would bust the clip and that it would fall off of me while I was wearing it, so I ended up not using it.  I think it would be fine for thinner women, however.  (my waist is probably about 35 inches or so)
