Wear 2 Shades of Eyeliner
To get Marilyn's signature cat eye, focus on your lower lid. If you look closely, you'll notice that she extended her liner out a few millimeters, mimicking a shadow of her false lashes. She typically used brown or black Elizabeth Arden pencils to create this wide-eyed look, then filled the gap between her upper and lower lids with a light color for a brightening effect. Try this at home using Elizabeth Arden Beautiful Color Define and Highlight Eyeliner Duo in Golden Sands ($23).
