Cinderella is a gorgeous light blue creme with pink glass flecks. The application was good and opaque in three thin coats. Its absolutely lovely in person. I love the combination of pink and blue.
Sinful Colors retail for $2 at Walgreens (online/in store) and Target (in store). They're also available for $2.50 at Cherry Culture. Cinderella was made part of their core line, so if you do not have them at your local store yet, they will show up.
