So far my summer nail colour of choice has been China Glaze's "Refresh Mint". A light mint green creme from the Spring 2010 Up & Away Collection. I had to hunt this bad boy down all over town because the Sally Beauty Supply where I get my China Glaze polishes was out. Eventually I ended up ordering it online from http://www.head2toebeauty.com/index.html.
Here's me wearing the shade while on vacation in Florida in May.
