Stila makes the best eye shadows in the world in my opinion. Most of the color are vivid and versatile to use which is a big plus. Since I never wear any color according to the season, I find it very easy to wear all these vibrant colors from stila. Cassia is a lovely baby pink shimmer eye shadow, and unlike Tango (another stronger hot pnik which I also like), it's a lot softer and sheerer. You can wear it as a base color, highlighter, or as an over all color. It's a very popular color that is constantly out of stock. If you can't find it from your local counters, you can also purchase it from sephora.com. Apparently, sephora.com is offering a one time free shipping on any order of $25.00 or more. And the promotion code is :FREESHIP8. Enjoy your on-lien shopping.
