No matter what the dress code is, some folks will be determined to flaunt it because they believe their "rights" are being abridged.
Recently there was a woman on FB castigating her daughter's school for requiring shorts to be fingertip length. Well she said her daughter had long arms and she simply could not find any shorts that long. And, of course, her daughter could not wear longer pants (too hot) and she didn't "like" to wear skirts etc. etc. When challenged by commenters that bermuda shorts were everywhere, she responded that her daugher didn't "like" those either and thus, she was entitled to wear short shorts. I guess she told them.
I'm sure her daughter will be charming when she eventually gets a job.
