Some of the following may have been answered in the book, which I haven't read so...
1) You are selling off some of Michael's iconic stage costumes citing storage difficulty and a lack of interest from museums as some of the main reasons to do so. However, at any point, did you try offering them to Michael's Estate? I'm sure they would have been happy to take them as they have plans to open a permanent museum someday.
2) After the Julien's catalogue was published, you mentioned (and so did Michael's Estate) that after careful consideration you are donating a few of the most iconic pieces to MJ's Estate. Can you please tell us which ones they are?
3) For public functions, Michael dressed up, but at home he really dressed down - in baggy t-shirts and all. Did Michael like to shop for his casual clothes or were these specifically made for him as well? If Michael shopped, what were some of his favorite places and brands?
4) Were there any celebrities whose dress style influenced Michael and he spoke of with you and Dennis Tompkins when discussing new designs for him?
5) Do you know the style he preferred for women? I read he liked women to be really dressed and done-up - think Elizabeth Taylor. Is that true?
6) A lot of people and celebrities try to emulate Michael, including his fashion. What did Michael think of people - celebrities, who copied his style?
7) Michael's fashion evolved over the years. In the last years of his life, 2007 - 2009, he was rocking Ed Hardy and Balamain, and even pulled-off wearing women's jackets! What was his fashion focus during these years?
8) Was Michael more a Boxers or Briefs guy?

And what was his favorite brand?
I might add more questions to this list, so watch this space...
