The image of Katy Perry has been fucked with, the eye on the right has been photoshopped to look uneven. Taylor Swift is ugly, but it's because of her personality and not her face. The second photo of the arab eyebrows is just as laughable as the photo of KP.
I agree with everyone else. But i also see what you mean, kinda. I am white, and i have a hard time shaping my eyebrows, as the hairs are sparse but long.. not a good combination. I think many other white women have the same kind of problem, but maybe not as bad as me.
The one of Katy is photo shopped. Taylor's... I don't know, that's just how she likes them or plucks them? And just because two white female celebrities don't have eyebrows to your liking, it doesn't mean all white girls have bad looking eyebrows. I think it's really immature to judge people based on their eyebrows, or to give someone shit for the kind of eyebrows they have. Some people simply can't grow full and nicely shaped eyebrows. Some people don't know how to pluck theirs into a nice shape. Some people don't know how to fill them in properly. Not everyone is a makeup guru, and not everyone actually even gives a shit about what their eyebrows look like.
