What to wear on your first day of work?

If the company has a business formal dress code, men should wear a suit and tie with dress shoes, while women should wear a pantsuit or skirt suit with closed-toe shoes. If the company has a business casual dress code, men can wear slacks, a button-up shirt, and dress shoes, while women can wear slacks or a skirt with a blouse or sweater and comfortable, closed-toe shoes.

Keep in mind that it's always better to be overdressed than underdressed on your first day. You can always adjust your attire based on the company culture and expectations in the following days.

Here are some general guidelines for dressing confidently on the first day of work:

• Go for a polished look. Choose an outfit that's sleek and tailored. Whether that's a fitted pair of dark jeans and a nice shirt or a blazer with dress pants, the point is to wear clothes that fit well and look fresh. Don't borrow a button-up shirt from a friend who's a size larger or smaller than you.

• Iron and starch. Starching, and in some cases even ironing, is becoming a lost art, but doing both will really help you pull off a polished, professional look. In fact, a recent survey revealed hiring managers were 43% less likely to promote an employee who wore wrinkled clothes, according to CareerBuilder.

• Choose classic accessories. Neutral accessories with a timeless style can really tie a look together and make you look and feel more professional. Think leather watches, handbags or briefcases, and simple jewelry. If you have extra or unusual piercings, take them out - 32% of hiring managers are less likely to promote an employee with piercings other than traditional ear piercings.

• Be colorful. Now that you're hired, you don't need to dress quite as neutrally as you did during your interview. Guys, it's okay to add some color with your shirt, tie, chinos, or socks. Ladies, go ahead and wear a colorful pair of close-toed shoes or a printed blouse.

• Take a conservative approach. Of all the things you can do to make hiring managers less likely to promote you, dressing provocatively is the worst offense of all. Avoid sheer fabrics, short hemlines, or clothing that fits too snugly--that goes for you too, gentlemen. Ladies, cover up a favorite sleeveless blouse with a cardigan or blazer.
