This is 2 coats of Jessica Pajama Party.
Pajama Party is a dark blue based purple shimmer.
Availability: I bought this in a set at TJ Maxx. Apparently it's from the 2010 Paint The Town Collection. I'm sure they still float around on eBay or Amazon.
Price: This is horrible, but I can't remember. I think that the set came with 3-4 polishes and was about $8.
I then added 1 coat of Maybelline Lavender Sparks.
Lavender Sparks is a light purple glitter polish that is a bit sheer and has holographic glitter hexs.
Availability: Most drugstores and retailers that carry Maybelline
