Parvati had done a lot of prep for this meeting. To keep all possible encounters between her husband and her friend to a minimum, Draco had gone to his mother's for breakfast on Parvati's request. He would arrive back only towards the end of the girls' makeup session, or even more likely, only shortly before it was time to leave for the luncheon.
Wilhelm, the couples' most stern faced elf, popped into the bedroom to notify Parvati of Hermione's arrival. Immediately, she put down her wand that she was curling her hair about and rushed down the immense master staircase.
"Hermione!" She greeted cheerfully as she entered the parlour, moving forward to the hug the other girl, "You look lovely already, why there's barely anything I have to work on!" The difference between pre-wedding and post-wedding Parvati was simply that she seemed calmer and held herself like an elegant woman rather than a flighty girl.
