You’re either trying to hard or not at all.

Are you wearing your daughter’s jeans and applying make-up the way you did when you when you were in your 20s? Or have you gone to the other extreme—walking around in frumpy clothes and giving off that vibe that says, “I just don’t care anymore.”

Going one extreme or the other are some of the problems that plague woman over 40, image consultants say. If you want to look fabulous for you age, avoid these mistakes.

6. Dressing like your daughter—Many of you are revealing way too much cleavage and showing off body parts that are best left covered. At a certain age, it just doesn’t look good, says Natalie Jobity, owner of Elan Image Management, an image consulting business in the Washington, D.C. area.

“There comes a time when it looks like you’re trying too hard,” Jobity says. Short skirts and tight pants, even on the best of bodies, are too much, she says.

5. Losing all interest—“My clients are the ones who have gone the other extreme, where they’ve given up,” says Ginger Burr, a Massachusetts-based image consultant and author of the book Fashion Secrets Mother Never Taught You.

She says many women over 40 are frustrated because it’s hard for them to find great clothes. Don’t give up, she says. It may be frustrating, but there are plenty of great clothes for women whose bodies have changed. You may just have to look a little harder.

And if you have given up, try going to an image consultant or a make-up artist.

4. Going heavy on the face paint—Make-up needs to be subtle; otherwise, you run the risk of looking older than you actually are. “I didn’t want to change my make-up,” says Veronica Lane, a 42-year-old Los-Angeles-based make-up artist. “I had to change my make-up.”

Lane says women make the mistake of wearing foundation that is too heavy—something that can add years on a face. Dark, heavy eyeliner is also out of the question. It’s just too aging, she says. Browns, grays and plums are better than black. She says women over 40 need to update their make-up.

3. The natural look—You may have been able to pull this off when you were younger, but when you’re over 40, you have to wear at least some make-up, Jobity says. “In terms of projecting a polished image, your face has to be done.”

2. Wearing the wrong bra—Are you pouching out of your cups or are you just hanging low? Either way, the image consultants stress the importance of wearing the right size. Your clothes will look better and you’ll look taller and slimmer.

Showing off bulges, dimples and other unflattering signs of an aging body—Be mindful of undergarments. They camouflage a multitude of sin and age and make your body look fantastic in clothes.

1. The wrong mindset—This may be the biggest mistake, says Ana Murillo, a 42-year-old image consultant in Phoenix. “It’s attitude, really,” she says. “When we feel good about ourselves, when we know who we are, we don’t have to work too hard.”

Study says bouncing boobs stretch permanently.

There’s Botox, cosmetic fillers, laser peels, and plastic surgery. But one potent, often overlooked weapon in the anti-aging arsenal is a good bra.

A woman can shave years off her age just by wearing the right-sized bra with the proper support. But a bad bra, research shows, can actually lead to sagging.

A study out of England showed that wearing the wrong bra can damage a woman’s breasts and stretch them permanently.

Researchers at the University of Portsmouth found that most bras aren’t designed to cope with the stress of bouncing boobs.

The lead scientist on the project told the BBC that women need to be aware of what can happen when they exercise without properly supporting their breasts.

“People rightly spend time and effort to get the right footwear for exercise and it is equally important to wear the correct sports bra,” Dr. Joanna Scurr said.

Her team discovered that breasts bounce a lot more during exercise than what was previously thought. They can move up to 8.26 inches during exercise, either up and down, side to side or in and out. Without the proper support, all that movement puts stress on the breasts and stretches out fragile connective tissue known as Cooper’s ligaments.

And contrary to popular belief, most sports bras don’t provide more support than traditional bras, the researchers found.

The study recommends that women of all sizes wear sports bras that encapsulate each breast and that women get professionally fitted.

Finding the right fit, however, remains a problem for many.

It a widely known fact that most women aren’t wearing the right bra size, says Linda Hogan, vice president of sales for Lunaire, a Manhattan-based lingerie firm that sells to voluptuous woman.

A good bra, she says, is supposed to lift a woman up and keep breasts from looking saggy. Too many women are “riding low” because of a bad fit.

“If you’re not up, you’re not wearing the right-sized bra,” Hogan says.

You’d be surprised by how many women mistakenly think they’re wearing the right bra, she says. As one example, she cites a job candidate at Lunaire who thought she knew a lot about bra size until the company gave her the right fit.

“When we got this girl into the correct size she literally looked like she lost 20 pounds because she went up.”

Many women are wearing the wrong bra because they’re in denial about their true size, she says. Often, they don’t want to be perceived as being too big or too small. But if a woman prefers to think of herself as a size C, as opposed to a CC or even a CCC, she’s going to be literally busting out of the cups, and chances are her breasts are going to look larger than she’d like. She’s also going to look heavier and older.

A good fit isn’t hard to find. Hogan says all you have to do is go to a department store and ask a salesperson for a fitting. It could just save your breasts.
