I really like a majority of makeup from the Flirt line. Not only are the products well pigmented, they go on smoothly. The color selection is a bit edited, but the colors are quite rich and pretty. The one thing I've been reaching for the most lately is their cream blushes. There's a really pretty red blush with gold shimmer called (I think) Madame X, and it's quite pretty!
I also like picking up some of the look cards from around that area for inspiration.
I've also played around with the American Beauty line a little bit, and even though their colors are a bit muted, the products are still quite nice. They have some illuminating liquids that are also quite pretty. I think it's called Luminous Liquid All-Over Face Glow, and the color that I liked the most was Gold Glow. It tends to go on a bit heavy, so it would probably be best to use this with a VERY light hand.
