Accentuate a Beauty Mark
Marilyn Monroe unwittingly followed a real estate mantra -- location, location, location -- when it came to the natural placement of her beauty mark. This beauty mark became known as the one spot Tinsel Town just couldn't resist, and rested on the left side of Marilyn's face, forming a nearly perfect triangle with her nose and mouth.
If you weren't born with a facial mole (calling it a beauty mark just sounds better, doesn't it?), then feel free to fake it. You can buy beauty mark kits online, or you can use a dark brown pencil eyeliner or liquid eyeliner to add your own dot. Just do it sparingly and consistently.
