An old favourite: Revlon's Strawberry Electric.
Strawberry Electric is a slightly-blue-toned, pearly pink shade. It is the regular Revlon polish formula and I've had it for years - still going strong! (Not sure if you can tell, but I've used over half of the bottle!)
From memory this took two coats. Easy to apply - can always rely on Revlon polishes. They are my second favourite to OPI.
