A double chin can make your whole neckline look thick and stumpy. Your aim, then, is to make your neck look as long and lean as possible. One way to do this is to keep your neckline free of hair. That can mean choosing a short cut -- something with lots of chunky layers draws the eye up and away from your chin. It can also mean wearing your hair up, giving the illusion of a longer, slimmer neck.

Keep your makeup focus on the eyes and cheeks. Doing so draws the eye upward to your amazing eyes or flushed cheeks, taking emphasis off your neck. Be sure your brows are groomed impeccably, and then use neutral eye shadows and plenty of soft liner and mascara to add eye definition. Or go for the flushed-cheek effect by applying color to the apples of your cheeks; in this case, dress eyes with a coat of mascara only.

Attempt to contour. Heavy contouring (the kind you tried in seventh grade to make your nose look slimmer) is too obvious. Instead, go for the subtlest touch. Dust a bronzer powder in a light shade along your jawline, under your chin. This creates a shadow, which in turn makes your chin look less conspicuous. Sweep some bronzer over your temples and nose to keep the look natural.

Avoid tops that stop just below your neck, as they'll emphasize your double chin. Crewnecks, boatnecks, and high v-necks are all off-limits.

Pick tops that elongate your neckline. As with your hairstyle, your choice of top can make your neck look longer and leaner (and your chin less noticeable). Go for tops with deep v-necks or scoop necks, or wear open-collared button-downs. Another option: A high turtleneck that camouflages your double chin.

Choose accessories wisely. Chokers that pinch your neck, long earrings that end alongside your problem area, and neck scarves all draw attention to a double chin. Instead, pick pieces that elongate and draw the eye away from your chin, such as a long lariat or necklace, sparkly stud earrings, and scarves worn away from the neck.
