Casual Friday is no longer just a “Friday” thing at many organizations today.

Not only are companies large and small– from start-ups to advertising agencies– embracing a casual uniform, but previously conservative companies are shedding their power suits and button downs, even listing casual dress as an employee benefit in a job description. Jeans are a commonplace staple of many work wardrobes. And who’s to say that, in those industries, that’s a bad thing?

Here, though, is a pitfall that But some people disregard the casual dress code to mean no dress code at all, so here are a few rules of thumb to consider as you scan your closet looking for something to wear to work.

7 Rules of Casual Dress:

  1. Work is not the club. If you’ve ever worn it to the club, or have thought about wearing it to the club, it is not office-appropriate. It doesn’t matter if you put a camisole underneath it or a jacket over it.
  2. Work is not the beach. If a dress has ever been used as a beach cover-up, or you’ve worn those shorts over your bathing suit, then the look is likely too casual, see-through or short for work. Save these items for making sand castles!
  3. Work is not the gym. T-shirts, sweatshirts, yoga pants and running sneakers are typically too casual for the workplace.
  4. Skirts should be of appropriate length. If your skirt hem doesn’t reach PAST your fingertips when you’re standing with your arms at your sides, then it is too short. This is one of those age-old rules, and you should stick to it.
  5. Distressed is okay–sometimes– but ripped is not. If any part of the outfit is see-through or ripped, then it’s not for the office. This includes thin skirts, cutoff shorts and ripped jeans, to name a few.
  6. No one piece should make your outfit professional. Wearing a blazer, closed-toe pumps or a scarf does not suddenly make an outfit appropriate. Besides there being a high likelihood of you wanting to take the jacket or scarf off during the day, an outfit should be pulled together by its pieces, not by a singular item.
  7. Grandma knows best. If you wouldn’t feel comfortable seeing your grandma while wearing it, don’t wear it to work. This by no means says that you can’t be stylish. My grandma was a very stylish woman. This just means you should be conscious that what you wear makes an impression, for better or worse, on the people you interact with throughout the day.
