I used to wear only foundation and mascara, but I was never seen without it and felt very uncomfortable not having it on in front of other people. I grew up in a church that considered makeup to be immodest, so even the small amount I wore was done in secret. But I was very self conscious about my acne, hence the foundation, and then that made me look a little washed out so I would do the mascara to bring a little definition back.
Now, I wear a lot more when I plan to "be seen", ie. at work, going to parties, etc. And I wear absolutely NONE other times, e.g. going on casual outings with my family, running errands, etc. So I've moved from "a little, always" to "either a lot or none".
When I put on makeup, I wear: tinted BB cream, under eye coverup, powder, blush, eyeliner, brows, lipstick (I like bright shades). Sometimes eyeshadow, which as taken me the longest to get the hang of, sometimes bronzer (I'm fair so I really just wear a dark shade of blush as a bronzer), sometimes a shimmer powder on my face or highlighting pencil on my lower lashline and tearduct. I don't wear false lashes because I don't enjoy that look, but I like that I can flex my makeup look to suite my mood or feel comfortable in none at all.
