Like many anime costume designs, this is probably one that you would have to heavily modify a pattern, or draft one yourself. The fabric portion does not look terribly complicated- it looks like a simplified kimono without sleeves or okumi and a thin trim/bias tape.
What I would do is use a guide for making a simple kimono- like a yukata. Read it, and then take the ideas and modify them to make your costume. for my Inuyasha build, this is one of the many sources I used to understand the fundamentals:

I did not use the pattern or methods, but it helped me to wrap my head around the concepts. For the different colors on the costume there are several ways you could approach that. Applique or fabric paints are two that come to mind.
