Who's ready for a little comparison? I sure am, so let's get right to it!
Two coats each, with top coat. So you see that while they have the same kind of sparkle, rock the boat is lighter and thus the sparkle is more visible. I also feel like there are more flecks in rock the boat than in bikini so teeny. But maybe that's just because they're more visible in rock the boat. In any case, these are not dupes, though very similar.
