Katie is described as "Gray, Green and Pink Polish! Fine to medium microglitters."
For this mani, I used Sinful Colors Last Chance as a base and topped with Katie for a reverse glitter gradient. I love how these colors all work together and pink and green is one combo that I am really liking right now. This polish was really easy to create a gradient with and I will definitely be doing more of them with ShimmerPolish in the future.
You can purchase Shimmer Polish on her etsy site, or follow her on Facebook or her website!
