I'd say go with a color like this: http://www.cosplayanimewigs.com/12hereshwigc.html
As for styling, if you think you can, style the curl yourself. There are some great tutorials on these forums on how to do it. I just tend to not like how the styled wigs look online, and I know I would rather do it myself. But someone here may be able to show you a place you can get a good one if you'd rather not do your own styling.
Hope you do cosplay him and have fun!
