1. Dress thinner by wearing monochromatic clothes. Wear one shade or variations of one shade from head to toe to create a long (thinner) line.

2. Wear a V-neck top. It creates the illusion of a longer neck, which gives you a slimmer overall look.

3. Avoid pleated pants. No matter how thin you are, pleated pants add bulk to your middle, making you look larger.

4. Try A-line skirts. They skim over your hips, smoothing lumps and making you appear more streamlined.

5. Wear proper undergarments. Too-small bras and panties that pull make lumps under clothes; underwear that fits well gives a smoother, skinnier silhouette.

6. Stick to straight-leg and boot-cut pants. They make legs look trimmer than tapered pants do.

7. Wear pants on the long side with heels. Cropped pants with flats can make you seem squat. Heels with longer pants have a longer, thinner look.

8. Go for jackets that fall below the hips. They lengthen and slim your body.

9. Avoid baggy clothes. While you may feel like they cover your least favorite spots, baggy clothes actually make you look bigger than you are. Fitted, not tight, tops and bottoms create a thinner line.

10. Pay attention to grooming. It's true: The more polished and pulled-together you look, from hair to makeup to nails, the slimmer and prettier you'll appear.
