4. Smallest Waist.
American Cathie Jung wears a corset 24/7 — and she has the waistline to prove it. Without a corset, her waist measures just 21 inches, but with it on, that measurement goes all the way down to 15 inches. Incredibly, though, Jung only holds the record for smallest waist of a living person; the all-time record, held by the late Ethel Granger, was just 13 inches.
