You start with the eyes, because they say those are the windows to the soul. A touch of mascara perhaps, some eyeliner, and slight dark eye powder to give you that smoky look.
Then the cheeks. Bronzer, right on the cheekbones, to highlight (or create) sharper angles. A little red coloring, to mimic (or fake) a schoolgirl blush.
Don't forget the lips. Full lips, but not red since you don't want to appear like a whore. A neutral brownish, reddish hue perhaps, just to emphasize its voluptuousness.
Then Spanx, to create curves where there was none before. A push-up bra, to lift sagging breasts, and to create the illusion of heft. Over which you throw the ubiquitous LBD, which effectively showcases your apparent feminine sensuality. Five inch pointy heels that can double as a lethal weapon.
You look in the mirror and smile. With a flip of your hair, you turn, ready to conquer the world. Game face on.
