Dress Codes in the Workplace

Recently the Missouri House changed their dress code in a way that only impacts women Representatives.

Changes mostly focus on requiring women to wear a second layer of clothing, with covered arms and shoulders being required at all times. There seems to be some disagreement as to whether it must be a jacket/blazer or if an open front knit top counts.

It’s now being vigorously debated in session. Is this simply a waste of everyone’s time, or is it important to outline exactly what should be considered professional dress?

What about other jobs?

Other than for safety purposes, has anyone dealt with restrictive dress codes?

Is “professional dress” an antiquated concept or still necessary?

Do dress codes need specific guidelines or are basics like cleanliness enough?

Are dress codes sexist or otherwise discriminatory?
