Rebecca Minkoff
At Rebecca Minkoff, the Haven Spa nail team, working with Essie polishes, created what they called a "Double Reverse French." It consisted of painting nails with two coats of Jazz, a taupe shade, followed by a stripe of Wrapped In Rubies and one of Midnight Cami, to create a shimmery, bejeweled finish at the tips.
