"Her Face is Young - but her figure betrays her age!"

"Before wrinkles show in the face there is usually loss of muscle tone in the torso muscles which support the vital organs.
"The diaphragm may pouch out, the hips spread, and the waistline thicken into that settled, middle-aged look.
"Keep your figure young by guarding the muscles."

Ad for Spencer Corsets, from 1927.
