Last month I could go to Kyoto and experience putting on real oiran clothes for the first time. I just loved how they used so many different patterns with challenging colors and mainly red-based harsh make-ups - nothing like I have been tried before (soft-pastel colored elegant, solid kimonos, etc.). It was so inspiring
I think Kyoko would definitely wear a gold-scheme uchikake (the big sized robes oirans wear outside) with sakura-flower patterns. (Usually the patterns and colors inside and outside are different: one is darker and the other is always brighter). I used gold paint for the uchikake and silver for her hair and kitsune tails but after scanning not much can be seen... :/
There are not many who suit well gold and silver at the same time but Kyoko is definitely that rear one who does
(also legends say that when a Kyuubi becomes a "kami" her fur is going to be gold). Also, yay for modern-retro feeling hats and accessories!
