Really perfect. Honestly.
Finely milled, with a slight sheen closer to Guerlain's Meteorites than most highlighters. The white is just that, a soft white that isn't metallic. The pink is even softer and lighter, a lovely cool glow. They're both so subtle I can't tell the difference on when I mix them.
Dior Glowing Gardens pink is warmer (peach/gold hint) and more metallic.
Camellia de Plumes is more metallic, silver, with a hint of warm gold.
Guerlain Meteorites is slightly more subtle.
