Butter London Rosie Lee is my pink of choice. I once saw a fab post showing Rosie Lee over a nude as a v-gap mani. I'm not so good on getting my V's centrally placed, so I opted to dot over a nude and have a whole pink nail as an accent.
My base is Nails Inc Basil Street, which went on in one coat. The Rosie Lee nail is two coats, although to be fully opaque with no visible nail line it probably would have benefited from an extra coat.
