While someone in a design firm is likely to dress differently than someone in a law firm, both share something in common: if you stray far from what’s considered the norm, you can be viewed as disrespectful and even as holding your employer in contempt. That won’t do much for your career. Think about making a statement that is professional and one that will be taken seriously for the work you do.

Always consider where you are going within the company. The image that you portray can help you meet your goals, or get in the way.

If you are wearing your company jacket outside of work, think about what you are doing. When people know that you work for a particular place, they expect certain things. If you suspect that you might do something foolish, don’t wear your company gear outside of work.

Although it may take an investment of time and effort, learn to look after your things. Iron like a pro and get rid of that slightly rumpled, still-in-college look. Replace it with an image that is crisp and professional. Find a tailor and have your trousers or skirts properly hemmed. (You’re spending good money on clothes as it is, so respect yourself and present yourself well.) Replace buttons if they go missing. Make sure that you are cleaning clothes according to the instructions on the label.

Shoes need to be in good repair and clean. Don’t wear your weekend or gym sneakers even on casual days. Make sure you have a polishing kit and that you know how to look after your shoes to keep them looking like new. People notice your footwear. You can lessen your credibility significantly by wearing a nice outfit and a poor pair of shoes.

Long-time glasses wearers have a gift for being able to look through a pair of smudged or dirty lenses, but your customers, colleagues, and manager will notice that layer of grime. Keep a microfiber cloth handy to keep your glasses clean.

Workplaces take professionalism very seriously. It’s in everyone’s best interests to maintain a professional atmosphere. While you may think you look good in club wear, evening wear, or lingerie, none of these are appropriate office attire. It can also be distracting to the rest of the office. Whether we like it or not, low-cut blouses, tight pants, short skirts, see-through fabrics, poorly fitting bras, ill-fitting suit jackets, or open shirts can contribute to a poor professional impression rather than an appropriate one. At work, the goal is to create an image of competence and professionalism; leave the glamor and glitz for your evenings out.

Nothing is more off putting than being greeted by someone with bad breath, so make sure that you brush your teeth, floss, and get regular dental check-ups, which are huge culprits in creating bad breath. If you are a coffee drinker or have a spicy meal, make sure you have something handy to clean yourself up. And don’t rely on gum: business people should not be chewing gum in the office, in meetings, nor blowing bubbles out on the step.
