My mother did sewing and alterations to help with income. No sisters and many times I was used as the dress form to hem when the skirt or dress was in my size.
It was back in the late 60's and I would often wear a panty girdle, bra stockings and slip along with heels during the hemming. She thought nothing of it, it was just a way to make money.
I started really liking it and would stay in the lingerie a little to long after the fitting was over which did not go unnoticed. Soon after my mother got a dress form from a second hand store and I was out of a job.
