Cosplayers: How would you recognize Shion from Higurashi better?

I am cosplaying Shion Sonozaki from Higurashi no naku koro ni for Jacon 2009 and i wanted to know which outfit would be more reconizable to you if you saw it. Either A. her school outfit (blue skirt, on down shirt and striped bow tie) or B. the regular outfit (black miniskirt and white sleeveless turtleneck). Either one will have the green wig and a knife and will have blood splatters on it.
