/cgl/ - Cosplay & EGL

I have two things I need help with.

FIRST: Cosplaying a character who's hair is just about buzz-cut, so a wig isn't really possible. (see pic) I did a test shave on my hair, but my hairline is more 'trapezoid' and less 'm' shaped. What would be the best way to go about achieving the hairstyle? Mess with trimming? Attempt to shape the hairline with careful scissoring? Since it's so short, a wig is pretty much impossible.

SECOND: I have a pair of Arda wigs that I was given by a friend. They're totally untouched; friend just ended up never wearing them. For whatever reason, they just... Don't seem to sit on my head right? I have other brands of wigs so I'm pretty sure it's just an Arda thing, but I can't really describe it. They feel fine, but when looking in a mirror, they just look weird. Any tips on how to fix this / similar experiences? Should I just sell them for cheap and try to get a different brand?
