Spring 2013 Comparisons: Orly Coachella Dweller vs Jessica Lime Cooler vs Essie Navigate Her. No dupes here either, Lime Cooler is more yellow toned and a lot brighter compared to Coachella Dweller. Navigate her is more of a pistachio green, it's more murky and yellow toned. I think you probably don't need all 3, I myself like Navigate Her the best of the 3! I used 2 coats for Navigate her and Lime Cooler and 3 coats of Coachella Dweller for the photo below.
The PolishAholic: Fall 2013 OPI, China Glaze, Zoya & Essie Comparisons - OPI DS Lapis vs Zoya Sunshine vs China Glaze Skyscraper. Sunshine and Lapis are fairly close, the base is a bit different though..Sunshine is more like a denim blue and Lapis leans more metallic.
