It kind of depends on what I'm doing or where I'm going, on a daily basis, I just have powder, so I don't get shiny or red. And chap stick, of course.
If I'm going out, I'll bring powder, concealer, eyeliner, and whatever I'm wearing on my lips.
When I'm traveling, like flying somewhere or going on a one-day road trip, I bring everything (primer, foundation, concealer, eyeliner, eyeshadow, mascara, and powder) so that I can put the makeup on at the other end. Like I never wear makeup on planes (aside from powder) but in the bathroom at the destination, I trick myself out. And in the car, I'll put my face on about an hour before we get wherever we're going.
I carry mascara and eyeliner, but only because I'm always running late in the mornings, and put it on as soon as my car hits park at work. A quick swipe of each is all I wear, unless we're counting Burt's Bees lip balm.
I have a small make up case in my purse, so I carry it all. Mascara, eyeliners, foundation, eye shadows, lip gloss and all the brushes that are needed.
I always wear makeup when I'm going out. I also carry..foundation, powder, nail polish (in case I chip a nail), 6 different colors of lip gloss (i only wear 2 though, lol), blush, a mini bottle of lotion, a nail file (that can also double as a weapon)
