Even more than Mia, I think Phase!Macha was a project that I loved since I first fought against her in the games... the spoilers around Mia and her, her wicked and bizarre design, hardly translatable to reality, a mix between computer-ish and organic was truly a challenge that I enjoyed very much. The mask with lights was also completely new stuff for me, but it's a very flashy and attention-drawing prop ^^ I painted it in a completely different way the second time I wore it, and sanded it to death XD
The wig was a really difficult challenge: my first try with the structure failed and the second one was done the same day of the WCS preliminary x_x It looked more or less decent, but I didn't have enough time to cover all the five (pink!) foam cores and the wiring lost hold at the end of the day. I then spent months restoring and re-dyeing it, and created a completely different method for the structure. I also re-did meticulously all five ponytails using 5 pieces of polystyrene, carved and painted, and then covered with a ton of hair fibers from other wigs, also dyed. I also added a couple of self-made wefts to the front of the wig which makes it look better ^^
Among other things I did the second time I wore this costume were retouching little parts of the eyes in the skirt, re-painting the zentai with much more detail (and now it looks actually purple and not almost black XD), doing the bone-like things below my chest again from scratch, re-making the Installation Book and more misc things I'm probably forgetting about x_x
