A Businesswoman's Guide to Dressing for Impact

Canaday says women are judged more harshly than men, because people don't automatically make the connection between women and business, and because fashion tends to sabotage businesswomen all too often. Strappy open-toed sandals or sleeveless blouses might look good in the Barneys' store window, but not in the boardroom.

She offers the following tips to make an impact in business and avoid any fashion carnage.

• When in doubt, bring the jacket out. Purchasing one or two jackets to layer over an outfit can immediately streamline your look. Choose a neat, up-to-date style.
• Speak loudly but tone down the attire. Stay away from loud, colorful or overly bold patterns, says Canaday. Avoid the whimsical and flowery, especially if you are petite in stature. Go for power-neutral colors like black, ivory, navy, rich olive or charcoal gray.

  Tone down the volume on the jewelry as well, because if it's too flashy it can distract from your message. "Stick to classic, understated pieces," Canaday advises.

• Be well groomed and well rested. Grooming is just as critical as dress, says Canaday, so keep your clothing pressed, clean and wrinkle-free for an organized look.

  Likewise, body language is often overlooked as a key component of overall image, for both men and women. High energy level is critical because people associate it with "a certain sense of power, authority and success," says Canaday. There's no better way to detract from that than lack of eye contact and slumped shoulders.

• You don't have to be boring. If you need to come off as more creative for your profession or just want to add personal flair to your outfits, hair and shoes are a fantastic way to add style yet still look highly professional. "A new, fresh haircut can do wonders for a woman," says Canaday, who recommends shorter styles or pulled-back longer hair. Long, flowing hair may say social, but not necessarily professional.

  The primary way men judge another man's success are his shoes, Canaday believes, and the same goes for women. Don't be afraid to show some style here. "Because it's such a popular trend, I see companies that used to ban open-toed shoes now allowing them," says Canaday. Still, stay away from towering platforms or strappy stilettos.
