Index to pinkie: OPI DC Cherry Blossom, OPI Hottie Pink, OPI Elephantastic Pink, Sally Hansen Flamingo
OPI DC Cherry Blossom: This is the brightest and most pigmented of all these polishes. It applies almost like old-formula OPI and it's such a gorgeous true hot pink.
OPI Hottie Pink: This was an Ulta exclusive from a few years ago, it's a softer hot pink that is definitely on the cool side of the spectrum. This is three coats.
OPI Elephantastic Pink: I love this polish so much I can't tell you. I have a thing for elephants though. However the yellow in this pink polish makes it soft and wearable, it's great for warm-toned people. It's really different than your average hot pink polish.
Sally Hansen Flamingo: The Salon range is gone, but you can still find these discounted in drug stores sometimes. I got mine for about $1. It's a bit darker on the nail than the others, but I like the formula. Two coats will do. And I like the warmth of this polish a lot, it really does remind me of a Flamingo, which I guess isn't surprising ;P
