I wear makeup every day of my life. I feel naked without makeup and earrings! My makeup is pretty waterproof (and so are my earrings LOL), and I don't wear a lot, just enough to make me look a little healthier than I usually do. I have very blotchy skin from some childhood illnesses, and it makes me feel much better. I never go anywhere without eyeliner and mascara, but sometimes that's all I wear (except for sunscreen, 12 months a year). I might leave the house (or my room) and not do my hair, but I never leave without doing at least a quick bit of makeup.
