The other problem I was having was cleaning and upkeep of the foam hip. They would get sweaty, then smelly and the best I could was air them out till dry and spray cleaners to disinfect and cut any smell. I know to much information but it a needed concern.
got a pair of pants that I was willing to cut up and were high waisted.
found the low point above my garter tattoo.
Off with the pants and cut the pattern seen here as the template.
sewed around the foam shape keeping the fabric tight.
