Carol was raised with the lie that all men wanted was "a woman who always dressed like a lady and obeyed orders" by her father. This is why for the most part, Carol never wore pants or shorts for that matter. As a child, she attended Catholic schools and would wear her uniform, even on days of free dress.
When asked why she was still wearing the uniform by piers, she responded that it was "Personal preference". She became the class president when her father bribed several kids in her class to vote for her, after she told him that she was not interest in running.
