I'm being generous with the 2.5 or even a 2. Not sure why I put it at 2.5, other than I respect Meghan Masterson for giving it the ole college try. The concept was brilliant. And even some of the research was pretty cool (although I wonder if she research primarily on Wikipedia). But the writing was redundant and the characters were flat, blah.
So the premise is about a young girl who is fairly wealthy and is the wardrobe mistress of Marie Antoinette (hence the title). The French Revolution was a bummer for many involved, and those who were against the revolution were to fear for their lives, as well as their heads. Oh, Marie did not suggest her people eat cake, by the way. It was falsely credited to her, and I guess she didn't care what they ate. I learned a lot about the importance of what she wore, though. Politically important. And the King was kind of an idiot.
I wonder if I hadn't read America's First Daughter first if I would have had a better impression. It took place in the same time period and crossed the same people (Lafayette), and definitely had a different writing style (different authors, so that makes sense). I'm not sorry I read it, but I don't think it was a great book.
