awee, your dress sounds cute! ummmm, try a darker, shimmery shadow, like dark brown. make it appear darker on the bottom lid and lighter as you reach your brow bone. use black liner on the bottom, corner rim of your eye, but not fully under. line your full top lid thinly. use black mascara (Maybelline works best for me), and a blush that appears the best on your skin tone, but not too dark. finish off with a shny lip gloss, if you think it will look right.
leave your hair down, but try and volumize.. like with curls. hot rollers work best for me. (Hairspray section of hair, then roll).
hope this helps!! :]
