The question I have for you is if you could ban the use of makeup for everyone would you? That's a harder question than it seems.
This is a tricky question because while I love and greatly prefer naturally beautiful women, I also appreciate the ART behind great makeup.
I don't mind a girl wearing makeup from time to time as long as she can go WITHOUT it and still be confident.
I will say that the word "beautiful" should not be applied to ANY woman who doesn't look genuinely STUNNING without makeup on their faces.
With that said, no I wouldn't ban makeup.
