I think you need another picture of that shimmer.
I thought I'd add some random stripey things in different colors. I started with a Nail Art striper in Frosty Pink. It went on really sheer and didn't really look darker until much later. I wish I'd gone a little thinner and lighter with the stripes. I'll know next time that it changes over time.
Next, I took another Nail Art striper in White and did a similar pattern next to the pink
This Nail Art striper is called Urban Legend. It's a magenta-purple color. I put it mostly over the white to help it pop.
And then, I low-lighted the pattern with some black for contrast.
Finished with Seche Vite topcoat, and there you go.
The sales clerk at Ulta gave me a nice compliment, and said I should charge to do nails! I don't think I'm there yet. If I screw up my own nails, I keep acetone at the ready, and no one gets hurt or angry! If you like it, I hope you'll try this and tell me how it went.
