I love this version of Homura. (I call it the Homulilly version, as she was a witch by then.) Apparently this was her funeral dress, prepared herself. Perhaps she went to the Tower of Cocoon already prepared for her death. The colouring is also spectacular. Black and white (in the original movie it was white, not RAINBOW - gosh! I prefer it white)... with a dash of red of the spider lily. It reminds me of blood.
