When you're going on vacation, a gel manicure is your best bet for chip-free fun. But on my toes, I prefer the Revlon ColorStay Gel Envy ($8). After a week at the beach, the two-step system stood up to sand and seawater. The application is simple with no UV or LED light required, and it comes off easily with generic nail polish remover. The Revlon range also comes in stunning Summer shades like white, green, pink, and bright purple.
