Yes, there should be a dress code. The dress code is that you should be WEARING pants. (Unless you chose to wear a skirt.)
If the waist line falls below your butt checks, you aren't wearing pants. They are pulled down and that is indecent exposure.
It's pretty simple.
A funny aside: we saw some boy wearing his long shorts like this and my 5 year old daughter said, "Mommy, why is that boy wearing a skirt". I couldn't stop laughing. Even she can see how stupid they look.
