Why do we have tuck our shirts in #2

In 10th grade last year all boys had to tuck their shirts in last year. I don't think it right because girls didn't have to tuck their shirts in at all they could have wore long shirts. When the boys did shirt in it made them look just like a clown in school. here again the school making up another crazy school rule that didnt make no sense at all. I just don't get at all some dress code are just getting out of hand.
