Imaging a woman as graceful as one of the most decadent Queens of France existing in the 21st century doesn't really work. The regal life isn't what it seemed to be back then, which is why the modern depiction of Marie Antoinette dressed as a headstrong, savvy business woman is a little weird.
But that's not to say she doesn't look stunning - her fair skin and even fairer hair make her look even more delicate than how she seemed when she was surrounded by decadence and refinery in flowing floral gowns. Whilst in her own time, she comes across as fairly demure and sultry, in our time she looks a little like a frightened rabbit that knows she is so far away from home. Let's hope she never actually runs away in a time machine.
