You don’t.
How do I tell a girl that she would look sexy playing the drums, wearing a leather skirt exposing the sexy legs, pumping the bass with her heels?
Yeah anonymous you're the guy that wanted a girl playing the the drums in a prom dress...... You're a sick ass whole!!!!! Now get lost you're not wanted here....... See ya wouldn't want to be ya
Why would you want to do that anyways... The girl will obviously feel extremely uncomfortable
