For this mani, I used Life in Plastic, As If, and September 2013.
For the base, I started with a layer of As If, which is a gorgeous milky baby pink holographic with strong blue shimmers. My bottle is a decant, so I can't accurately speak to application issues. After this base layer was dry, I then took my handy Elmer's Glue that I put into an old Seche Vite bottle and painted the skin around my fingers. I did this to make cleanup later easier. Now, once I've finish the mani, all I have to do is peel off the glue, and it'll take the excess paint around my fingers with it! I swear by this trick every time I do a gradient and often times when I do stamping. It's a huge time saver in the long run!
After laying down a base layer of As If, I then sponged on a gradient using As If and September 2013. September is a medium pink linear holographic with a slight golden flash. I sponged on two layers of gradient, which came out nicely.
Next, I added on a layer of Life in Plastic, which is pink shimmered neon pink glitter topcoat. Application was a tad difficult because the glitter to base ratio is a bit more in favor of base to glitter. I had to dig out some of the glitters, and even then I had to deal with pooling on my skin. It definitely required cleanup, but that wasn't a deal breaker for this mani since I already had to do some cleanup for the gradient.
September is no longer available, but LiP and AI do pop up at EP's suppliers every once in a while. Otherwise, you can find them on blog sales.
