I applied the same base and top coat on both hands, the left with one coat of this color, and the right with two. Right away I noticed a difference in that the hand with one coat looked much nicer. It could be a fluke, I dunno....but I had some tip shrink right away on the right hand, and it wore unevenly. When I wear this color again, I'm going with the one coater. It held up amazingly over the course of 4 days, I'm really liking this new formula so far.
When I bought this color, I was thinking that it looked very similar to Zoya Natty, which I already owned. I bought it anyway, because I love this color, dupe or not! When I looked at them side by side, I realized that Natty is a deeper, darker shade of stormy blue. Bottoms Up is a bit brighter. Below is a comparison.
