What is business professional?

Business professional attire is a formal dress code common in more traditional workplace settings. Industries such as banking, accounting, government, finance and law typically require business professional dress in the workplace. Business professional clothing might also be appropriate for job fairs or networking events where you know the attire to be more formal.

​

Business professional attire for women

Women following a business professional dress code should wear pressed slacks, skirts or dresses, sharp button-down shirts or tidy blouses and blazers. No matter the look, solid, neutral colors such as black, gray and navy are best. Keep any accessories minimal, avoiding items such as chunky jewelry or oversized belts.

​

Depending on your outfit you might also decide to wear hose, especially if you’re wearing anything other than dress pants. You should also consider polished, closed-toe shoes with a maximum three-inch heel and a neat, professional hairstyle.

Here are several additional tips and options for women’s business professional attire:

​

Skirt or pantsuits

A pantsuit is an excellent option for professional dress. Select a clean black or gray pantsuit or pencil skirt and blazer. The garments should be comfortable but fitted, with skirts falling just below the knee.

​

Business professional shirts

Opt for a collared, button-down shirt with your pantsuit and blazer. Select a neutral color like white or blue. Button-down shirts always look professional but must be pressed. Wrinkle-free fabrics are a great option for a business professional office.

​

Business professional shoes

Whether you prefer flats, pumps or heels, choose a shoe that has a heel less than three inches. Black patent pumps or loafers are an enduring option. Pair your shoes with hose close to your skin tone when wearing a dress or skirt.

​

Professional women’s accessories

Select minimal jewelry such as stud earrings or a simple cuff. Ideally your belt should match your suit and blend in under your blazer.

​

Business professional attire for men

Business professional styles should include subdued, solid colors. A good example of professional dress is a dark-colored suit and tie with a light blue or white button-down shirt. Match your belt to the color of your oxfords or loafers.

Choose a conservative tie by avoiding overly bright colors or busy patterns. You might also invest in a few pairs of dark socks and a tidy hairstyle.

​

Here are several additional tips and options for men’s business professional attire:

​

Business professional suits

The perfect business professional suit is solid or pinstriped with plain or cuffed bottoms and notched lapels. When in doubt, choose a black or dark gray suit for year-round wear and a medium gray or deep blue for the summer. Avoid light-colored suits, however, as they’re more appropriate for social events such as weddings.

​

Business professional men’s shirts

Good shirt options include solid white or light-blue to medium-blue button-downs. Always consider your company’s dress code before trying to incorporate new elements you’re unsure about. No matter the shade, your business professional shirt should feature a French or barrel cuff to which you can add minimalist cuff links.

​

Business professional ties and accessories

Keep your tie simple. Solids are a great starting point, but classic, conservative patterns and stripes are also appropriate. Business professional shoes include loafers, oxfords, monk straps or classic cap-toed shoes in black, brown or burgundy.
