This color is from the Burlesque Holiday 2010 collection from O.P.I.. It is a beautiful deep pink with pink sparkles. Although not an exact dupe for Bad Fairy (The Show Must Go On is slightly deeper pink), you would be hard pressed to tell the difference without painting two separate nails with each.

The color is gorgeous, and also shines different under different lights. Taking on an almost red appearance in deep warm light. In cooler light (like outdoors) it's more pink.

I think O.P.I. hit the color just right. It's a pink that would be great for the holiday season. My sister in law couldn't stop complimenting my nails. Like most glitter polishes, it was sort of a pain to remove. The sparkles are thicker and slightly bigger than MAC Bad Fairy sparkles.
I'd actually like to apologize for the delay too, I meant to post this on Thursday, but for whatever reason my wifi refused to work all last week so I couldn't get online. Hopefully I have no issues this week.
So what do you think... Does O.P.I. The Show Must Go On have a good resemblance to M.A.C. Bad Fairy?
