i would say dont wear jeans or pants! a skirt is more fun, even if its a jean skirt with leggins! wear a pretty top (nothin too revealing or u will look like a tramp) and some jewelry. a necklace or a few bracelts or earings r always fun. and always always always wear comfy shoes! flats r fun, and dont wear heels to a cas dance they hurt too much! and dont wear sneakers they r too casual. and wear some makeup but not toomuch so tht it looks like u r trying too hard
