We may all say “not to judge a book by its cover,” but the truth is that appearance makes a big difference in the workplace.

Wrinkly slacks, that boho lace top, or a much-to0-short hemline can make the difference in whether someone hires you and invites you to the big kid’s table in the boardroom. Do you want to build a reputation based on your edgy fashion or your professional ability?

I beg you– please save your fashion freak flag for Friday night. Or get a job with a creative firm/ bar/ fashion designer that accepts your inner fashionista.

With that out of the way, let’s be real… professional dress code terms can be confusing! What is the difference between business professional and casual? What should you wear to an interview? Are jeans acceptable on casual Friday?

Your first couple of weeks, it is best to play it safe and err on the side of more conservative dress. See what your co-workers wear (especially the ones who are respected and in leadership) and use their standard as your guide. Regardless the workplace culture, here are some general rules of thumb to guide your fashion choices:
