Dress for success: Defining business and lab-appropriate attire

What does “business casual” mean and how can you find the right balance between comfortable and professional, especially in lab or research environments? Whether you're preparing for an internship, a day in the office or time in the lab, dressing appropriately sets the tone. Here's how to confidently navigate the expectations of business casual, and what that means in both professional and lab settings.

What business casual is

Business casual is a flexible style of dress that falls somewhere between formal business wear and everyday casual attire. Without having to wear a full professional suit or dress, this style is slightly more relaxed and allows for a wide range of options.

Typical business casual outfits might include:

  • A collared shirt (such as a button-down or polo)
  • Sweaters, blouses or cardigans
  • Dress pants, khakis, chinos or a knee-length skirt
  • Closed-toe flats, loafers or dressy sneakers

For more specific examples and styling tips, MasterClass offers more detail into how to pair these together for an office setting.

What business casual is not

There are some clear “don’ts” when it comes to business casual. While certain styles of jeans may be appropriate in some workplaces, they should never be ripped, faded or distressed. Certain shoes like flip-flops, casual sandals or running shoes are often suggested against, unless your company dress code states otherwise.

Other clothing items that fall outside the business casual dress code include:

  • Workout clothing (leggings, yoga pants, gym shorts, etc.)
  • Crop tops or shirts that expose your midsection
  • Transparent or low-cut clothing
  • Graphic T-shirts or shorts

When in doubt, it’s better to dress up a little more than necessary. It's perfectly okay to ask your supervisor or mentor what’s considered appropriate, especially if you’re new to the workplace culture. If there is no dress code available, Indeed has a list of common business-appropriate attire by industry.

Business casual in the lab

If you’re working in a research or laboratory setting—like an ORISE Research Participation Program—you’ll want to consider both professionalism and safety.

Start with the basics of business casual but factor in lab safety requirements. If you are unsure of the attire needs, be sure to ask your supervisor or mentor. Some examples of what might be appropriate are:

  • Wear long pants or jeans (without rips or holes)
  • Choose long-sleeved shirts when appropriate
  • Avoid loose clothing or accessories that could be a hazard
  • Keep hair tied back if it’s long
  • Always wear closed-toe shoes

Protective gear like lab coats, safety glasses, gloves and hearing protection may be required. Be sure to follow your lab’s dress policies and ask your mentor if you’re unsure. Athletic shoes might be acceptable in some labs but double-check to ensure they meet safety standards.  

Dressing appropriately is a subtle but strong way to show that you take your role seriously—whether you're in a meeting, the office or conducting research in a laboratory setting. Your attire should reflect respect for the work you're doing and the people you’re working with. So, when reaching into your closet, remember to dress not just for the job you have, but the one you want.
