Sissy is a feminine male.
Feminine clothes are attributed with feminine traits, which are stereotypically, submissiveness and weakness. A guy who wears feminine clothes, would be abused as a "gay" because he wants men to control him like they control other women.
Badass is a masculine female.
Masculine clothes are attributed with masculine traits, which are stereotypically, dominance and (physical) strength. A woman who wears masculine clothes is therefore, badass, but I don't know about "hot."
