Oh glorious glorious gradient ! I was inspired by @lemmingspolish (check out her work here) for these nails and used some pretty cool colours for it too. I used Ulta3 Lily White as a base and then China Glaze In A Lily Bit, Highlight Of My Summer, Too Yacht To Handle and OPI You're Such A Budapest.

Once you get the hang of doing gradients, the possibilities are endless !
Here's a video tutorial from a previous gradient I did.
