Also, I just finished (well about a month or so ago now) reading Miss Pamela's first book again after about 20 years after the first time around, and she mentions this outfit.
There's the whole series of him in this white/cream colored velvet fringey thing and she said that she made it for him. As she was describing it, I immediately thought that it had to be this one. She mentions the fact that he posed for a photoshoot in it, so I think it has to be this one.
Anyway, just more useless information there I guess.
