Fairylite is a great stand-in for Shimpagne skinfinish. Buffed into the skin it gives a great glowy look. It also makes a wonderfuly body shimmer, hair highlight, and nail color.
Also, for future pigment purchases, you may wish to take a look at the precautions list (linked in my signature at the bottom of this post). It gives you all the usage precautions for every pigment ever released by MAC, as well as a few other products. The list includes true-to-life swatches, and a FAQ at the bottom of the main page which explains what precautions are, some usage suggestions for pigments, and other helpful topics.
