I’m a rising senior there. Dress code enforcement is really dependent on your teacher, but if you break it, it’s just a tardy, nothing big.
I’ve personally had no bad experiences with it. Most clothing is appropriate; just don’t wear, like, sweatpants or athletic gear. I know girls have more problems but seeing as you’re asking about male clothing, that doesn’t seem to be a problem.
If you want to wear shorts, they shouldn’t be of the athletic kind. Think of something around the same formality level as jeans as appropriate.
By the way, dress code doesn’t apply outside of class hours, so during, for instance, orientation, you can wear whatever you want.
Good luck!!! If you have any questions, feel free to reach out! I can send you the exact text of the dress code privately, if you’d like.
That’s the water polo psych!
