Brief meta: I think that my semi-answer/comment about George Sand may have suppressed the initiative of others to respond with proper answers. So I am going to post this as an answer, even tho I think it is not a great one to try and undo my un-intended derailment. Perhaps it will prompt someone to do better than me.
I just listened to an "In Our Time" episode on George Sand who, two centuries after your question, found she had to dress as a man both to go to the opera unaccompanied and to mix in society enough to gain material as a writer. For Sand in particular there are other factors at play tho: She grew up riding on her grandmother's estate -- in riding trousers and it would certainly seem that she enjoyed bending gender norms.
If the George Sand example can be relied upon it seems entirely possible that two centuries earlier members of the order were prompted to take such action.
