I'm not familiar with Naruto, but do you perhaps mean the one above?
If so, you should be able to alter a pattern from the fabric store in order to get that look. I'd say to check out some of the simple jacket patterns (I can't find the pattern brand/number that I have which may be helpful-- sorry). Definitely look out at JoAnn Fabrics around the holiday time since they tend to have really nice deals where you can buy patterns for $1 as opposed to $16.
The jacket/vest wouldn't be too hard depending on what your preferred fabric choice is and your skill level (if you're a beginner, it might be a tad difficult) and if you have a sewing machine (the level of difficulty may be higher if you're sewing it all by hand). If you're looking into making it from twill, you could be looking at around $7 a yard. Pleather would be a little more (an you may have to check out some online stores since that color is pretty hard to find-- at least when I go fabric shopping when doing commissions, I have a difficult time finding that color). Though these prices are off the top of my head and might depend on your local stores. The cost of the fabric will also depend on your size.

If anything, you could also make a post in the wanted commissions section with your measurements to get quotes on how much a commissioner or fellow cosplayer would charge to make it for you.
I hope this helped!
