/cgl/ - Cosplay & EGL

I'm cosplaying as Barazo Mankanshoku from KLK for a con this year. I got a good feeling what to get for my cosplay but to cut down costs, I'm thinking of growing my hair for his hairstyle and let a supercuts do the rest. Anybody know what kind of hairstyle it is and how long of hair do I need to style it?

First time cosplaying in a long while, and I'm planning to cosplay as 2 characters but I dunno what kind of thing is which.

First one is Mako's dad from KLK, what kind of clothing is the jacket? ie: tuxedo jacket, etc.

And also, for hair as simple as that, am I better off letting my hair grow out or just getting a wig?
