Estée Lauder’s brand-new Little Black Primer is just as versatile as your LBD. Wear it alone for a little bit of curl, under your mascara to minimize smudges and flakes, or as a water-resistant top coat for extra pigment. The primer’s uses carry it from day to night, making it a must-have makeup bag staple. $24, at Neiman Marcus, Nordstrom.
