I'm a female and this is what I wear daily:
1. concealer to cover up any zits. if I have no zits, I wear none.
2. one smudge of brown eye shadow, and sometimes I forget this.
advantages:
1. it takes me 35 seconds to get ready to go anywhere
2. travel lightly
3. does not run off my face when I sweat
4. my boyfriend enjoys waking up next to someone who looks the same as she does while running, grocery shopping, going out to dinner, hanging out..
5. I look better than 99% of the skanks who pile on the makeup
disadvantages:
...I see none.
I have the confidence (mostly through running) to not give a crap if my looks aren't up to anyone elses standards. I think I am pretty. Sure thing that I look tired some days, I look awful when I'm hungover, sometimes I have zits that no amount of concealer can fully conceal, but I don't mind. It's life, I'm not gonna try to cover it up to look perfect.
