I ended up liking this purple more than I expected to with two coats of Borghese Bella Berry — lots of shimmer and that great deep purple shade.  Then used some Milani Diamond Dazzle to sparkle up the middle finger.  Super thick sparkle polish, on eyeballing it in the bottle it struck me as a bit more “general sparkle”… but turns out putting it on such a deep bed of purple made it pick up all the colors of the rainbow in the little flakes, so one to grow on there.
