I love this design. Kind of psudo-Japanese. Lots of Japanese elements but some other fanciful elements as well, like the poofy skirt and bustle like thing. Kind of a cross between England and Japan (which is exactly what the Mikado was anyway, right) The colors are wonderful, and the pattern is outstanding. "It does take the top off things, you know."
I LOVE the Mikado! My favorite play ever! I've actually done quite abit of fanart for it myself.
So I was browsing through your gallery, and when I caught sight of this picture, "Three Little Maids from School" immediately popped into my head and got stuck there. Then I saw your comment on it and I laughed out loud. So I'd say you hit the mark.
Aside from that, it's a beautiful design. Great details.
