About the Word:
Although silk clothing remains expensive, silk stockings were truly luxury items in the 19th century and earlier. Even Thomas Jefferson (the face of the $2 bill) made a slightly mocking reference in an 1812 letter to "silk stocking gentry."
Fancy cars and private planes are more obvious markers of wealth now, but the term silk stocking is still occasionally used as it was when Jefferson was writing.
