Prospect High School's dress code is sexist. Many of the requirments are aimed at female students, and often males who break the dress code have no punishment whereas females do. 

The Student handbook states:"Clothing such as halter tops, tube tops, sleeveless undershirts, strapless tops, spaghetti strap tops, low cut tops, racer-back tops, backless tops, tops with one shoulder, bare midriff tops, crochet tops, swimwear, short shorts, short skirts, underwear worn as outerwear, low riding pants displaying boxers or sweatpants;"

The only goal is getting rid of things that are a distraction to learning. Assuming male students will be distracted from their learning by seeing a females shoulders shouldn't be something that is being taught to be acceptable.

The only dress code should be:

Cover your privates.

That’s it.

Nothing else. No “shorts this long” or “shoulders this covered” or “shirts this long”.
