It's easy to do and looks pretty daring and edgy. If you can tightly pull the sides of your hair back, it would resemble one of those side shaved hairstyles.
My hair is not as thick and my top layers aren't as long as CL's, but I tried my best to imitate the hairstyle. It's not something I'd usually wear, but perhaps I'll save this for a future rock concert xD.
Have fun and thanks for watching! ^^;
P.S. I wanted to make a FAQs video this break too, but I don't think I can anymore. I have a big project to finish and it would take lots and lots of hours :l
