I hate to be cliché and trust me I want to start smacking people around when I hear stuff like this but -- gray is the new black for Fall 2008. MAC's Trend Spot write up during New York Fashion Week declared that purple and gray are the colors to have your eyes this coming Fall.

If you want to capture this trend here are some great products for you:

NARS Single Eye Shadow: NARS makes a great eye shadow, I don't know why I don't use it more. The color always goes on strong and has nice staying power. This color is perfect for Fall 2008 because it's a combination of the two hottest shades for beauty ... gray and purple.

Bare Escentuals Wearable Eye Kit - Meet The Stones This kit by Bare Minerals has all the gray eye shadow that you will ever need. If for some reason these colors don't work for you, try mixing and matching to achieve your perfect shade of gray.
DuWop Gray Eyes I love DuWop's eyeshadow kits ... mostly because they are super cute. This kit is perfect for getting your perfectly gray, perfectly smokey eye for Fall 2008.
Sephora Brand Enchanted Eye Palette - Plum I am a sucker for an eye palette, you get all you need and more in one neat little package. This palette will be your best friend in Fall 2008 because grays and purples are the "it" thing to have in your make up bag.
Urban Decay Matte Eyeshadow If you want color that goes on just like you see it in the container then Urban Decay is perfect for you. When I was in high school I bought a bright blue (I was in high school remember) from Urban Decay and that sucker went on bright! Probably a bit too bright for the way I was applying it but still.
