I always wear:
some kohl and mascara around my eyes, to look more "awake".
lip gloss or at least lip balm
quick brush and tidy of eye brows (Benefit Eye brow it)
no skin slap as I take my compelexion very seriously, and regularly do exercise and go to sauna so you get that lovely glow, naturally.
I also exfoliate and moisturise, and that way skin looks fine without foundation (am olive skinned so never get too pale).
On bad days I put on some face brightening powder (Dandelion, Benefit)and under eye concealer.
My DH would swear to anyone that I wear no make up and that he likes the natural look.
IMHO men don´t have a clue
So, I use make up to try and look prettier, yet natural, without looking like I have been made up IYSWIM
There are lots of women on the school run who look a bit grim in the mornings (some don´t even brush hair), and I do think they would look better if they´d only spend a few minutes looking in the mirror.
Then again, I guess I am a bit more vain than most....???? seeing the reactiosn on this thread!
