Use waterproof makeup wherever you can! Companies have some excellent products that keep that makeup from going anywhere.
Make Up For Ever aqua eye liners are fabulous
Layer, layer layer- this means using an eye pencil then going over it with a similar eye shadow. Use lip liner and then a lipstick, blot, lipstick ,blot, lipstick.
PRIMER - using a face primer and an eye primer is essential for any long lasting makeup. I love using Smashbox Photofinish Primer. They are all oil-free and great for making the skin smooth and flawless.
FOUNDATION when it is hot and you want it to last, I love using Cover FX Natural FX and MAC's Face and Body. These babies last under most conditions. Be warned - if you have super oily skin proceed with the aforementioned with caution. They do not work as well.
SETTING SPRAYS - Urban Decay De-Slick is an excellent one and MAC's Fix Plus
Wedding makeup is definitely individual. However, I am a firm believer of having the Bride looking like herself but glamorous.
