Why do I call this costume "Silver Millennium Princess Mars"? Well, Setsuna Kou, my costume maker, called it that first, and I guess it just stuck. But it makes sense to me--the long red gown is the dress she wears when she's a princess in Crystal Tokyo, under the realm of Neo Queen Serenity, and this is the matching dress she wears when she's a princess of the Silver Millennium, under the realm of Princess Serenity.
I still haven't mastered wearing this costume, though. The laces that go up my legs are so pretty--too bad I can't walk more than a block in them before they fall down. :(
To match the other princesses at NDK, Patti and Steph made me a new broach, so I swapped the gems out that Setsuna-chan had made me.
To match even MORE princesses (you can never have too many princesses) at AWA, Patti and Steph made us all new waistbands as well! (That can also double as Pope hats, apparently...)
