Several years ago I read a book that talked about the French Revolution (I can’t remember the title). When discussing the Flight to Varennes, the book said “If not for Marie Antoinette the venture would undoubtedly have succeeded” and blames her for wanting her luggage, insisting on bringing ladies in waiting and her hairdresser, and effectively forcing the King and herself to leave in a large, lumbering carriage with a following carriage for her staff rather than just taking a smaller, faster carriage by themselves. How fair is this assessment?
There's always more that can be said, but you may be interested in my past answer to During the Flight to Varennes, what mistakes did the royal caravan make that gave away their identities? The gist is that the flaws in the flight to Varennes were far more complex than the stereotypical "dumb rich woman" ones assigned to Marie Antoinette.
