I think it's great that you're confident in yourself. We shouldn't feel like we have to wear makeup because that's BS. I'm getting really fed up with advertisements constantly telling me I need to fix what's only natural and it seems like people are wearing more and more makeup as time goes in. That being said, putting effort into your appearance isn't a bad thing either if it makes you feel good. It's a tricky balance and one that I haven't figured out myself at 29. I always wear concealer in the winter because otherwise I scare myself, and mascara as well. Occasionally I'll go without eyeliner but that's only when I'm either a) in a great mood or b) really down in the dumps. I feel like I'm not helping at all, but you're not alone!
