The girls do not have to worry about guy ogling or molesting
them, they always have their favorite hotline: triple 9, whenever a
guy molested her so they would lure guys into such trap. It is
difficult not to be a perverted. If you are walking in a street and
she is in front of you, walk another direction or maybe just avoid
being around them, or maybe just go somewhere where there aren't
any such girls wearing those reavling clothes until someone
invented a medicine that guys can immue to ogling at girls after
guys have administered that tablet 
If those girls are in the same class as you, maybe you could
shift your seat so that you would not able to look at them or worst
possible, you could pray and hope that some scientist would invent
such pills that would enable guys to immue to ogling at girls, I
bolieve 
someone will invent it.
