Reese Witherspoon always has a fresh-faced look and rarely changes her look from the street to the red carpet - all she does is add a little red lipstick.
To get Reese's understated look you need to use shades as close as possible to your natural skin tone except for on your lips.
Use a pink blush that compliments your skin tone for a healthy glow and apply it in the style that best suits your face. Round faces look better with blush applied to the apple of the cheek, while narrower faces can take blush on the cheekbone.
To get glass-smooth lips, try brushing them very gently with an old, soft toothbrush. Then apply petroleum jelly and allow it to soak in for 30 or more minutes.
To add a little glam, choose a matching lip liner and lipstick in a wine or red berry that compliments your blush. Apply one coat of the lipstick and blot with tissue, then apply a second coat. Then, line the lips if necessary. Cover your lips with a coat or two of clear gloss.
