Was looked on as something shocking...
If a show has an episode set in the 1800s or early 1900s, or is referring to that era, expect mention to be made of The Ankle Taboo. This is often Played for Laughs; a picture of a bare ankle will be referred to as pornography, and the sight of one will induce much shock, scandal and monocle-popping. Other times, "can't show your ankles" will simply be used as short-hand to sum up all of the repressiveness of that era.
How much this was Truth in Television is debatable, since climbing stairs and getting into or out of carriages would probably lead to plenty of exposed ankles in everyday Victorian life, especially for working class women, and girls' dresses tend to have shorter hemlines and are expected to get longer once they come of age◊, and theatrical costumes often showed far more, at least until knee level, but it's pretty firmly entrenched in popular culture nowadays.
Note that a lot of things we tolerate today were severely frowned upon in those days (and vice versa), but the exposed ankle is probably one of the easiest, quickest, and (in 21st century culture) silliest examples of Values Dissonance that a show can portray, and thus works best for a quick gag.
