Amazingly enough, this entire costume was made with left over fabrics I had laying around. I was able to make two shirts out of it too; a long and a short sleeve.
The shirts are made out of some type of polyester and lined in a white cotton. The ties are a yellow cotton and are sewn in place, just to be on the safe side. The pants are a dark blue polyester with the same red fabric used for the ties at the ankles. The shoes are an awesome pair of taichi shoes I found online and they are super comfortable.
The wig is actually my second attempt and I am so much happier with this version. It's an Arda wig in Apple red with a short weft sewn at the base for the pigtail. I sewed a bit of fencing wire in the pigtail so I could actually pose it!
He's made of black moleskin, with vinyl hooves. The nose and bandanna are cotton with the designs appliqued on.
So this Happosai is to scale, at least to the best of my abilities since his size changes depending on scene/episode. I set P-Chan next to him so you could really see how much bigger he is. He's made of felt, I used batting for his hair, and appliqued on his details. He's wearing a cotton jumpsuit and a moleskin belt.
