flash of ankle

[hhtt21]

I am confused by the phrase "flash of ankle". Would you please explain it? Flash means "gleaming" and "ankle" the part joining foot and leg. I cannot work out "a flash of ankle".

"Not to mention largely confined to those who could keep a secret and were not scandalized by such things as a flash of ankle."

Sex workers in Victorian times in wealthier areas wore their shorts a little higher to offer a flash of ankle to let potential customers know.
