I'm the girliest of girls when it comes to makeup and products. I can literally impluse purchase 4 lipglosses and not think twice about it. However, I do have a few tried and true products that you will never find me without. Dior Show mascara being and a rich creamy brown eyeliner (brand doesn't matter here!).
I do must of my purchasing from Sephora - like Nars, TanTowel, Marc Jacobs perfume, and all my Time Balm products! You can't really go wrong.
