but the best way to do to it is to find a picture of it and try it out. Don't worry if you check out all the lastest beauty magazines EVERYONE is doing the smoky eyes! Check out the ads in Allure, Vogue, and Bazaar you will find someone who has the same shape eyes as you.
The young lady who I get my Clinique base eye shadow for my own smoky eyes got her ideas from Jessica Simpson. With the one from the makeup tuts here and the other ideas offered, I am sure you will be able to find just the right look cause only you know your eyes! Good Luck!
