Lip Liner-use a liner that is one shade lighter than your natural lip color. Ben Nye's Caramel Rose (If you're in LA, Nigel's or Frend's in North Hollywood carries it) or Mac's Subculture matches most natural lip colors. Line your lips and also fill
in lips with lip pencil.
Lipstick-It's always best to use a lip brush when applying lipstick. Or you can use your finger tip to dab it on (make sure you sanitize your hands.. Germs are everywhere and you don't want them in your mouth;) ). A good color to start off with it is Sandy Beach from MUD http://shop.mudshop.com/sandy-beach (the color shown on site looks much darker). Top it off by dabbing your lips with Freckletone (neutral peach/lustre) from MAC.
Gloss- You can do clear to keep the color or use a peachy gloss like Pink Lemonade from MAC for a peachy nude.
Don't be afraid to mix lipsticks together it's the only way to get your lip color to the exact shade you are looking for. Have fun and customize your own lip color. Annnd ....
Relax, It's just MakeUp! ;)
