For me, a must have is a paper bag with eye holes.
Really though, I just use regular Neutrogena moisturizer, then a little cg smoother in a couple places to lighten things up and then a little bit of cg foundation, a tad of blush, some powder and then a little lip gloss with light color in it. Although by the end of the day, a lot of it is worn or wiped off. I don't put a lot of effort in it. I have my makeup application down to a few minutes.
I have a blow dryer, but I don't use it. Its one of those neat ones too with a self retracting cord. I just wet my hair, rub in a little mouse, then fluff it with my fingers and spritz a little hair spray on it and let it dry while I get stuff ready to open at the store.
