I think you mean when their manager (and possibly the parents) started the production company. They were like six years old when that company was started. I doubt they had much to do with it. I don't really see them as self-made billionaires, but rather as mediocre actresses who had really good, ambitious management. They're surely business savvy now, though.
Anyway, I don't really like this particular outfit. I do kind of like the shoes, but I agree that it's amazing that she can run in them.
Well, the bag is marco tagliaferri... a milan based designer.. I have searched about him and is really hard to get hold of, was just wondering if there was someone here with more information about where to buy his bags.
