Rbadizza, you should wear length skirt with stockings and heels...definitely. Wear your hair back if it is long and don't forget the red lipstick. But if they want " short sleeve and knee length skirt.." just follow their advice - at least it will shows that you're able to follow orders strictly.
Be
confident and
smiley, without too much expectations - i think this is the right way to make a good impresions to the recruiters, everything else is a question of chance and luck.
Well, I wish you best of luck one more time
