May be this will be not very popular, but there are reasons males react this way to females in dresses in tech conferences. I agree that we all should have our mind more open, but by the age of ~25 we all got our stereotypes in our heads based on our family, sitcoms/movies, radios, school/friends, etc. This is no different from assumptions based on race, age, or sexual preferences.

I am afraid, there is no quick hack and culturally we as a whole should steer our perception. This is hard work which will take time.
