*EDIT 15-3-2012: finally got around to rendeer the colours more similar to the real-life one! I can't believe how long it took me to learn how to use Photoshop's tools XD*
This is by far the dress I most loved to make <3
It comes from Takarazuka's musical "The Scarlet Pimpernel", 2010 tsukigumi production, and is Marguerite's ballgown for the end of the first act ("nazotoki no game").
It's a two-piece+cage+crinoline construction made with interior taffetà (cheap and beautiful xD)
