Business casual sounds like a breeze — no more worries about what to wear to work, right? Not quite. 

In fact, this dress code guideline is a frequent source of confusion for workers. And it's not their fault — there really isn't a clear, standardized definition. Business casual may mean different things at different companies, cities, and industries. And on top of that, understanding the subtle differences between "business" and "business casual" isn't easy.


One thing is clear: Dressing in shorts and a t-shirt or a sundress and sandals is too casual. But wearing a full suit — and a tie, if you're a man — is too formal. When in doubt, it's better to err on the side of dressing too formally, rather than too casually. But where's the line?

Read on for guidelines that will help define appropriate business casual attire for men and women, along with general advice on what to wear, and what not to wear, in the office and during job interviews.  

Business Casual Attire Basics


Women should wear a combination of a skirt or dress slacks, blouse, sweater, twinset, jacket (optional), and hosiery (optional) with closed toe shoes. Sandals or peep-toe shoes may be permissible in some offices; flip-flops are never considered part of business casual. 

  • Khaki, corduroy, twill, or cotton pants or skirts (skirts should not short)
  • Sweaters, twinsets, cardigans, polo/knit shirts
  • A sheath dress is often flattering, and looks very professional
  • Solid colors work better than bright patterns


For men, appropriate business casual attire is dress slacks or chinos, a shirt with or without a tie, dark socks, and dress shoes. Avoid wearing polo shirts to an interview, even if they are acceptable for the job in question.

Do not wear jeans or shorts. 

  • Khaki, gabardine, wool, or cotton pants, neatly pressed
  • Cotton long-sleeved button-down shirts, pressed
  • Sweaters
  • Leather shoes and belt
  • Tie optional

Additional Dress Code Rules to Consider

Look Before You Leap: If you're new to the company, avoid dressing like you're heading to a picnic until you understand the company standard. Err on the side of being conservative rather than showing up underdressed until you check with HR or a colleague to determine what exactly business casual means for your company.

During job interviews, always opt for the more formal version of business casual. Even if you show up and your interviewer is clad in shorts or a short skirt, that doesn't mean it would be appropriate for you to dress that way. During a job interview, you want to make a good impression, and part of that is dressing professionally. There are some outfits you shouldn't wear to a job interview, regardless of the dress code.

Maintain Consistency: If you wear professional and conservative outfits Monday through Thursday, don't show up Friday looking unrecognizable. That's true even if your office has "casual Fridays." On casual Fridays, you can dress down a bit. It's often acceptable, for instance, to wear jeans.

But opt for your best jeans, not ones with stains or rips on the cuffs. Whatever you wear on casual Fridays should still be acceptable for a meeting with your boss or a client. 

No matter what kind of company you work for, maintaining a consistent image helps to establish trust and credibility with you as an employee.

Consider Your Calendar: If you're meeting with clients or scheduling a business lunch, dress on the conservative side out of to respect the people you're meeting with; save the casual comfort for a time when you'll be in the office all day.

What to Wear When There's No Dress Code

What do you wear when there's no dress code at all, and almost anything goes? How casual is too casual? Here are tips for both men and women for what to wear to work and job interviews when there's no dress code at all.

What Not to Wear

When the dress code is business casual, it's not appropriate to wear your favorite old t-shirt, ripped jeans, ratty sneakers, or flip-flops. Remember the "business" part of business casual, and leave your old comfortable clothes at home; outfits should still be clean, pressed, and fit properly.

Avoid clothing with logos or potentially offensive words or graphics. Men do not have the option to skip shaving or go without a belt. Women should not wear anything that's too tight, flowing, short, or low cut. Make sure that bra straps aren't visible. And it's a good idea to keep makeup natural and low-key.
