Counterintuitively, You Should Moisturize

Cosmetics guru Sonia Kashuk knows from slippery, slide-y bridal makeup: She did the honors at her pal Cindy Crawford’s 1998 wedding in the Bahamas—in late May. Still, she always recommends moisturizer. “You can go lighter,” she says, “but don’t forgo it altogether.”

Primer Is a Really Good Idea

Consider this a magnet (a breathable, comfy magnet) for everything else. It’s the layer between moisturizer and makeup, but if you’re concerned about oiliness, you can also add a mattifier to the lineup. One to try: Peter Thomas Roth Max Anti-Shine Mattifying gel ($35).

Liquid Is the Newest Take on Minderal Foundation

Though Kashuk feels base is optional—provided you’ve got great skin—makeup artist Ramy Gafni disagrees, citing the formality of the occasion. And he prefers longer-wearing liquids over loose-powder mineral foundations, which have a well-deserved rep for being light and airy. The best of both worlds? Liquid mineral foundation.

Gels and Stains Go the Distance

Whether or not you’re a crier, liner and eye shadow can smear and head south in the heat. To the rescue: gel and waterproof formulas (like the ones pictured here). For cheeks and lips, stains provide a similar stay-put insurance policy. Plus, they’re kinda great. “Gels and stains deliver a pretty, natural finish,” says Kashuk. “They become one with the skin.”
