So I'm committing on cosplaying as KH3 Sora to my local convention this year, and big surprise, I'm not finding too many promising leads on a good wig online. I was able to get a really good Roxas/Ventus wig from someone some years ago, but I think they stopped their business since then, for some reason. So does anyone know of any good resources I might try to get a KH3 Sora wig that's more or less accurate? Particularly any wig/cosplay artists who are open to take commissions? I usually just get my cosplay stuff from websites so I'm a little unfamiliar with the individual cosplay artist market.

I recently purchased a wig from Arda Wigs and am going to try styling it myself.  They look high quality and I've heard great things about them.  Beyond that, I would recommend Etsy.  I have seen some great ones on there, and while they're a little pricy I like the fact that it is supporting a person as opposed to a Chinese corporation.

Good luck on your cosplay.
