Dress in monochromatic colors head-to-toe. 

You may know that head-to-toe black is slimming, but did you know that head-to-toe anything will give you a slimmer look than chopping it up in blocks of color? Even head-to-toe white can be slimming.

Wear heels.

The taller you are, the slimmer you'll look. So add a few inches to legs with heels. If you have heavy legs, make sure you pick a substantial-looking heel.

Opt for back pockets on your pants, jeans-style.

The worst thing you can do for a broad backside is to go pocketless. Back pockets - the flat, jean-style patch ones - break up the expanse of bottom and make you look smaller.

Wear jewelry close to your face.

Bring all the attention to your face with earrings and/or a necklace. Long, layered chains to give the entire body a longer, leaner line.

Choose the right prints.

The wrong print is anything that makes you look wider: polka dots, thick horizontal lines or widely spaced florals. The right prints give you visual height - like pinstripes - or provide camouflage (like florals that are medium-to-large size and are tightly spaced together to show very little background.)

Use makeup to make your face look thinner.

Double chins are especially prominent as we age. Find a powder one shade or so darker than your skin tone. Use upward sweeping strokes to apply it under your chin to help that area recede. You can also use a bronzing powder (applied with a very light hand, and with only touching the ends - not brushing) along cheekbones and on the temples.
