Ok. I am a makeup "whore" in that I like different products from different lines.

The best foundation I have ever used is the matchstick by Prescriptives. I think they actually market it as a concealer. But, it is wonderful. It turns to a powder and hides any skintone probs you might have.

The best lipstick is a tie between Lorac (from Sephora.com) and Lipfinity by MaxFactor.

Eye shadow and blush are all about Estee Lauder for me. My grandmother always buys me the Estee Lauder makeup set they sell at Christmas. It lasts all year and has about 15 different colors of shadow and 3 types of blush. It also has mascara and some lipsticks. You might find them on sale for next to nothing now.
-- If not Estee, then I head to Wal Mart for the Rimmel cheap stuff. It is great compared to Loreal, etc.

For an actual concealer, if I look like death warmed over, is hands down Clinique conceler.

(Here's the caveat to the story... I have some of the oiliest skin on the planet and have to choose products that abide well with my skin type...)
