By Jennifer Weatherhead, Photography by Geoffrey Ross Name: OPI Nail Lacquer in You Don't Know Jacques The specs: A muddy-grey shade that transcends seasons. Why we love: As a self-proclaimed nail polish lover I usually switch up my colour a couple of times a week, and with the endless options out there, it's tough for me not to get bored with a shade. Not so with OPI's You Don't Know Jacques. Ever since this perfect grey shade hit the market over a year ago, I have been completely obsessed with it (I'm nearing the end of my third bottle). The perfect alternative to black or super dark nails, it fits my fall wardrobe nicely. And in the summer it's a great way to break up the usual hot pinks and pretty pastels that grace my nails. Where to buy: Available at salons and spas, $10.95. Need a mani/pedi? Before you hit the spa check out the latest options for getting your nails perfectly polished.
