/cgl/ - Cosplay & EGL

Looking for some wig advice.

I wore my first classic coord at a convention recently and I'd ordered a new wig. I needed to cut the bangs I was going to get a cosplaying friend to help because I haven't cut wigs before, but I ran out of time and had to do it the night before the con. I looked at a couple of tutorials but they weren't incredibly helpful, so I just cut the bangs straight across with fabric scissors. The result was a very blunt, square fringe that looks unflattering, pic related.

How would I go about fixing this, if possible? I did like this wig before I butchered it so I'd like to know if its salvageable.
