This is my first ever experience cosplaying!
I really wanted to be Princess Mononoke for Halloween. I've never cosplayed before so I wasn't sure where to start. I thought I'd just buy the costume online, but after seeing the price (800RMB) and the cheap material the costume was made out of, I decided to make the costume myself, and share my experience of becoming San for other-would-be Princess Mononoke cosplayers.

Step 1: Costume Components
For the mask, I opted to use paper mache and cover it with a layer of paper clay, following this amazing tutorial here: http://www.otakucrafts.com/2012/10/princess-mononoke-san-mask-tutorial/
Knife/Spear: I made a cardboard knife prototype, covered it with paper mache and painted it, again following this method by the same author as the mask tutorial: http://www.otakucrafts.com/2012/09/princess-mononoke-san-cosplay-mask-and-knife-progress/
Headband/armband: This was easy, I just used a black cotton strap I had lying in my scrap drawer, and affixed the paper mache circle left over from cutting the holes from the mask. As for the armbands, I just used some spare bra straps.
Necklace: I was lucky enough to find a cheap necklace in a shop that looked just like fangs, so I didn't need to make the fangs out of clay myself.
Dress: I hunted around online on Taobao (Chinese shopping site) for a suitable dress that would resemble San's blue one and I found one that had a skirt that tapered to a long point at the back but was shorter in the front. It wasn't exactly like San's dress but it would still work well.
Tunic: I got a cheap white tank top, cut off the bottom and slit the sides up to the arm seams, so it would fall open like San's tunic but wouldn't fall apart (pictures can explain this better than I can)
Shoes: This is something I could have improved on. I opted to wear brown leather boots since I'm a little on the small side and would like to appear taller. But these shoes look nothing like San's hide mocassins....
Fur cloak hood: Bought some fur online on Taobao, 75RMB for 50cm x 180cm, more than enough for me. :D
