Dressing for a job, an interview, an internship, a networking event, etc. is a source of anxiety for everyone at some point in their career. Each company and event are different, so it can be nerve-racking not knowing what the proper dress code is, what you can and can't wear, etc. You want to make the best impression, of course, and your clothes say a lot about you and who you are! Types of Business Attire There are 3 main types of "business dress" that you need to understand before we get into dressing for specific events. These are probably terms you've heard before, but after reading this, you should have a good understanding of what clothes work for what dress code. The three types of dress codes are: Professional Dress, Business Casual, and Campus Casual. Business professional attire is the most conservative type of business wear. It's what you'll be expected to wear in the office if you work in accounting, finance, or other conservative industries (or if you just have a really conservative boss!). This style is also known as "business formal." Business casual attire is a more relaxed version of "Professional Dress," but it doesn't mean you're actually going to be "casual!" This is likely going to be your office dress code if you work in a semi-conservative workplace, but some interviews and events may also call for business casual.
