I love blue (what a news), so some time ago I tried this combo...
I had something in mind, but you'll see it later.
"Royal", you all know it, blue and jelly... But I decided to add on top of it another "blue and jelly" gem, Shaka n. 800 "Glossy Blue".
This particular nailpolish has a lovely shimmer, very very fine, just like a fine blue diamond dust, which gives it depth and a really nice finish.
I hope pictures are showing this effect, in real life nails look like under a layer of a precious glass : >
Best performance? In the sun <3
Have a nice day/night/whatever and thanks for your attention ;¬)
