Jane was your lovely, loyal girlfriend. She and you had been invited to a Halloween party and of course you had to have matching couple costumes

as you arrived at the party you could already see people's eyes on Jane, maybe it was because of her short skirt? you tried to hide behind Jane everywhere she went and she noticed "hey babe is everything okay?" she asked, she was too innocent to know people were staring at her skirt. What do you tell her?
