GUYS: Do you like natural, smokey, no makeup etc?
Most Helpful Girl
I think that guys here who want girls to be natural have very rarely seen a girl completely natural... they've just seen girls with very little makeup on. Trust me boys, natural isn't as big of a deal as you seem to think it is. Natural makes some of us look tired and hobo-y. Very few girls actually look better naturally than with a little makeup on (mascara and a little concealer under the eyes usually does the trick). This is just my opinion.
Back to the question. I'd have to say that mascara is my favorite. If I had to choose only one makeup product to wear for the rest of my life, it would definitely be mascara. Even if your complexion isn't perfect, mascara still makes you look a little prettier and dolled up, even if it isn't all that special. Effortlessly pretty. :)
