My favorite nail polishes tend to be light, ultra-feminine colors. Black just isn't for me. One of my summer favorites is OPI's Suzi & the Lifeguard, a light pink infused with a subtle shimmer. Like all OPI polishes, this one requires two coats (unless you like very sheer color) but stays put longer than most. If you love glossy pinks, OPI debuted a new Pink collection this spring, featuring four polishes suitable for the office—or the pool. Most professional salons sell OPI, along with Trade Secret and Beauty First. --Dana Wilson
