Professional Attire Basics: Understanding Dress Expectations for the Interview and at Work

For some people in their first internship or moving into a new industry, learning about professional dress expectations and business attire can be daunting. What’s the difference between business casual and business professional? What’s appropriate to wear at a start-up? What if you prefer an androgynous style, or enjoy incorporating elements of formal dress from your home country in your work wear? This blog post will help you understand some of the basics when it comes to choosing what to wear to interviews and to work.

What Different Types of Dress Include

Sometimes it may seem as if every company has a different definition for their dress code. We find that in most U.S. workplaces expectations for everyday attire will range from a “dressy” casual style to business professional. While there are endlessly long lists of dress codes online explaining each type of dress in detail, these four categories are a good starting point:

  • Casual/Everyday: T-shirt, jeans, shorts, patterned skirts, and sneakers, sandals, or work boots.
  • “Dressy” Casual: Plain T-shirt or polo, light jacket or sweater, jeans or slacks, and sneakers, boots, or heels.
  • Business Casual: Button-up shirt or blouse, optional tie, sweater and/or blazer, khakis, slacks or skirt and closed-toe, professional shoes (not sneakers).
  • Business Professional: Matching suit in navy, dark gray, or black with a button-up shirt and tie, sweater, blouse, or shell and professional shoes. Note: Pant and skirt suits are each appropriate.

How to Choose What to Wear

When you’re dressing for the job or internship, it’s important to assess the specific workplace’s culture and norms. While the entry-level, customer service positions you may have held in high school or college often have an explicit dress code down to recommendations of which brand of shoe to wear, the expectations for professional positions are often vague. It’s important to research the company’s work culture and find out what most employees wear on a typical workday, then choose your clothes similarly. When dressing for the interview, wear an outfit that is at least one level dressier than this typical attire.

This chart can help you decide what to wear to the interview. Note that while some example industries and positions are listed, it is important to keep in mind the specific organization and even the region. Consider the company’s reputation, client base, and how they brand themselves. An advertising agency that specializes in skate and snowboarding companies could potentially have a different standard of dress than an agency that works with luxury resorts; this is why researching ahead of time can help you dress to demonstrate familiarity with the company culture. When in doubt about what to wear, always choose a more formal outfit than a more casual outfit.

Typical Workday Interview Wear Example Industries
Casual/Everyday “Dressy” Casual or Business Casual Customer service, construction, trades, some start-ups
“Dressy” Casual, Uniforms, and Scrubs Business Casual Tech, entry-level government or nonprofit, entry-level healthcare
Business Casual Business Professional Entry-level business, government, education; management-level customer service, construction, and healthcare
Business Professional Business Professional Management-level business, finance, hospitality

Navigating Authenticity in What You Wear

Our identities can play a large role what we wear and how we’re perceived by others. Being a woman, a person of color, LGBTQ, or a member of a minority religious or ethnic culture can mean facing pressure to dress more formally due to others’ perceptions of your professionalism. This disparity is unjust, however it is up to each individual to decide how to navigate choices about professional dress and appearance under that reality. Here are some tips that may be helpful in doing so:

  • Be comfortable enough to interview or focus at work. The advice blog Corporette emphasizes that “if you’re more confident and feel more professional in” clothes that differ from a standard interview outfit (such as a skirt suit), then “this may be the time to deviate from the norm” by wearing pants or a jacket that help you feel comfortable and confident.
  • Find mentors and advocates in leadership roles who have your back and can speak to your competence and skills.
  • Determine for yourself what your comfort level is for openly challenging the status quo (or not).
  • Exercise your best judgment when it comes to choosing clothing or making other decisions about your appearance for an interview or the workplace. Ask A Manager’s Alison Green shares in her advice about personal appearance that what matters most is looking “polished and professional”—whether that means wearing makeup or not, conforming to gender standards or not, or other considerations.
  • Familiarize yourself with different kinds of professional dress to help sharpen your eye for what is casual and professional. These Pinterest boards for “dressy” casual, business casual, and business professional are great places to start.
