I was reading an article in one of the numerous magazines that I get about waist size in conjunction with health. They pointed out the growth of the waist over the years. In the 50's they showed Marilyn - 22" waist. Wow.
In the 60's Audrey Hepburn had a 20" waist. Holy crap. I know one burlesque performer who has a teeny waist and in a corset is 16". I have never been below 28" since as far back as I can remember. To me it's freaking astonishing. I really never thought that people really had waists that small without girdles or corsets!
