Here is a polish I picked up at Walmart by Hard Candy called Mr. Wrong. Definitely the most famous of the Hard Candy line, and it's for a reason. This is one cool polish. Sometimes it looks silver, sometimes it looks purple. But all the time it looks awesome. Veryyyyyyyy sparkly. Go buy it! It's only five bucks.
[Edit: My apologies for calling this polish Mr. Wong. Apparently I have penises on the brain]
