That's awesome that you were able to quit. I have never worn foundation, I've never felt the need to. I have fairly clear skin, and my mom biased me against it, she is convinced it is bad for your skin. I'm also kind of afraid to try foundation anyway, it looks intimidating to me too. But lately I've wanted to try a tinted moisturizer for some occassions, like if I'm getting pictures done or going to a party, my skin is looking a little blotchy and uneven (maybe it's stress and not sleeping well).
I think foundation can look good when the person has it applied, uhh, correctly. I know two girls who wear it regularly and they apply way too much. As far as I can neither of them appear to have bad skin, but I think the several obvious layers of it takes away from their skin, and I think they would look much prettier if they applied it with a lighter hand.
