OK. You know the part in the movie where she is changing into the dress to go rescue maurice...well she doesn't tie or button up the back. she comes out and says "yards of fabric and i still feel naked" well she should because her dress is not tied up. oops
Well, think about it. Have you ever worn clothing that buttoned or zipped all the way to the very top in the back? It's very hard to do by your self (it's the same with trying to scratch back there.) I think they intended us to think that she planned to have Gustaff (her friend) fasten it for her. And even if that small part wasn't fastened, she shouldn't have felt naked. What she meant was that the cloth was so much lighter than the heavy, woven material she usually wore. This isn't a slip-up.
I don't think that this was actually a slip-up. The girl was not yet finished dressing, notice when she goes to free Maurice, her hair is done and her dress is tied. I think you are looking into this a bit too much.
what most likely happened was off screen her freind helpd her finsih dressing. I'm in the SCA and I can state for a fact that there is NO way a person can get into that style of dress with out help, that's why the woman back then had maids to dress them.
I think Danielle felt naked because the dress was so much lower-cut in the front then a woman of her status would be used to wearing. I don't think that by the standards of society at the time, she should have been changing in the same room as a man, even behind a screen, or that she should have come out without her dress fastened, but Danielle wasn't ever in a position to learn "proper" feminine behavior, and what we know of her character shows she wouldn't have learned it even if someone did try to teach her. Total tomboy. I love it.
