Hi LisaMarie,
You can get some good tips by scrolling through the old competition advice forum postings.
Is there a female professional at your studio? She should be able to give you some help and may even offer to give you a makeup lesson. Our pro gave us a lesson before our first competition, and always offers to do our makeup and hair at the competition. She can do in 15 minutes what would take me two hours.
The basics she recommends:
-Foundation
-Bronze blusher under the cheekbones, and brighter blush on the cheekbones and apples
-Eye primer (Mary Kay makes a good one)
-Shimmery white shadow from the eyelashes to the brows
-Black shadow in a "v" in the outer corners of your eyes and going into your crease
-Shimmery brown shadow on your brow bone and blended over the black shadow
-Blend, blend, blend that shadow, and apply more white under the brow and in the inner corners of your eyes if necessary
-Liquid eyeliner applied with a felt tip on upper and lower eyelid
-False eyelashes, definitely!
-Lots of mascara, more than you normally use
-Bright lipstick, pink or red, depending on your coloring and your dress. I put lipliner on my whole lip and then apply the lipstick - it helps the color last longer
-Translucent powder applied with a large brush to seal everything
Best of luck to you, and have a lot of fun!!!!
