We all know that to create a more dramatic make-up, eyebrows are an important part of the process. I first became aware of this "fashion" of shaving eyebrows off by watching Adora Batbrat make-up tutorials. I didn't truly notice it before but since I watched the tutorials, I realised that many goths have in fact drawn eyebrows!

But drawing eyebrows is not a simple thing. Yes, you only need an eyebrow pencil, or liquid or gel eyeliner but it's the drawing the most difficult part.

Eyebrows have to be the most symmetrical possible, they have to have the same lenght and the same height and also the same amount of eyeliner. Also you have to check what kind of eyebrow designs suite your face the most. Otherwise you might end up looking like a clown or just looking dumb!

So to shave or not to shave your eyebrows off? Well, it's up to you, if you think you can handle designing perfect eyebrows everyday, if you think you have technique, do it! Maybe do some trials first. Cover your current eyebrows with a thick layer of foundation and draw them in a different shape. If you see you have no problem with it, shave it.
Otherwise you better leave them on, and maybe just make them more perfect with an eyebrow pencil or even with a dark eyeshadow! To be sure they are symmetrical you have to take measurement with your eyebrow pencil like in the picture below:
Good luck with your eyebrows! ^_^
