Character Name: Shinohara Natsuki
I'd been hearing good things about Summer Wars and curiosity finally won over at Anime North 2011 where I ended up buying it. I got home and enjoyed it so much that I watched it something like 3 times in 2 days.
I actually had the top red part done already from another costume that I never got around to finishing. The green part was made out of some scrap material and it snaps at the back. The hakama were made out of some type of stiff material (I don't remember exactly what it was). In retrospect, I should have made them out of something more malleable and I should have made the pleats deeper since they don't hold very well if I bend down.
I already owned the boots and the white tie. The ears were made out of felt with wire inside to hold the shape, which were then sewn onto a headband. The hanafuda cards were bought at a 100yen shop while I was in Japan and the wig was bought on Taobao.
