I can't speak towards the 11th century too well (too far back for me, do apologize), but there are some decent accounts of what Marie Antoinette went through in her transition from life in Austria to her life as wife of the Dauphine. She was 'switched over' rather abruptly. It involved a female 'aunt' like figure to guide her in decorum and tradition, a lady's maid, ladies in waiting, male advisors, change in clothing and appearance, and a run down of traditions in court. Marie was young, and despite this group of people to support her had great difficulties adapting to the rigid traditions and customs of French Court. Marie felt as though every moment of her life was scripted, particularly compared to a more relaxed atmosphere in the Austrian court.

Off the top of my head, Caroline Weber's work Queen of Fashion: What Marie Antoinette Wore to the Revolution, has some excellent passages to the description of this. The modernized version of Marie's lady in waiting, Madame Campan, The Private Life of Marie Antoinette also describes the process.

I do apologize for not being more specific to the 11th century, but hopefully this helps answer your question.
