Ah, love this look! The blue really pops over the nude and both are subtly holographic. The nude is Butter London "All Hail the Queen" (vegan) and the blue is LA Girl 3D Effects "Brilliant Blue" (vegan).
These flakies looked gorgeous over the dark blue, almost like a galaxy. The base is Zoya "Cynthia" and the flakies is Ludurana "Arco-Iris" (not sure if these is vegan or what).
