OPI Rally Pretty Pink is a truly royal pink with tons of golden shimmer. It has so much shimmer in it that it gives a duochrome effect to the nail polish. I wouldn’t say that this polish is a duochrome by itself though.
Rally Pretty Pink is a part of Serena Williams for OPI Slam Glam collection. It was supposed to be a base for the red shatter. For me, it didn’t work at all. Somehow, I thought that these 2 were not complimenting each other at all. Plus, I didn’t like red shatter idea.
