Betty Brosmer had a reputation for having one of the smallest waists in the world. Brosmer was most famous for this in the 1950s. She was a pinup girl who could be seen on countless record album covers, calendars, and magazines. Her waist was so small that she was able to win fifty beauty titles before she turned 20-years-old. On top of that, she had a busty chest and long blonde hair. Mix that with an ultra-thin waist and you have a very beautiful woman. Brosmer’s official measurements were 38-18-36.
