Yes, the US dress codes are still outdated and sexist. For example, there are some women who are not allowed to wear crop tops because they are “inappropriate” and yet, boys can wear ripped jeans and they would not be called “inappropriate” at all. If the dress codes will be implemented, there should be fair implementation which means that boys have a lot of rules to follow the same as the girls.
The dress codes in the past were a bit detrimental to girl students at that time because they were not allowed to express themselves through their clothes. Dress codes should be created in order to make the learning environment healthier and more uniform. If it would be implemented the right way, it will create a huge difference in the learning system.
