Tone down the rest of your makeup to make sure your smile is the star: Use concealer to even your skin tone, dust on a translucent pressed powder, and sweep on a blush that is just a shade or two pinker than your natural color. Finish the natural look with mascara.
Accessorize with off-white accents like pearl earrings or alabaster beads and charms. They're milky in color, so your smile will look especially white in comparison.
Accentuate your smile with lipstick in a true red shade or one with subtle brown undertones -- orange-based reds will only make your smile look dingy. If you have fair skin, try a red stain instead of lipstick, and top with a sheer gloss. For darker skin, pick a deep burgundy.
Draw attention toward the face with a V-neck collar or long necklace. Any button-down blouse will do the trick. For an extra touch of drama, pop the collar to frame your face.
Wear fabrics in the blue family, like dark purple, navy and gray -- natural highlighters for your smile. The color contrast will make your pearly whites look, well, pearlier and whiter.
