So basically, showing a little skin is acceptable, just don't over do it. You will save yourself and your date lots of embarrassment. Body jewelry and glitter are hot, if used in moderation. Butterflies, stars, and hearts are great prom accessories. And even a little shine in your hair can accent an outfit.
Color is always important.
Pastels, elegant blacks, silver and gold are the hot ticket. Just make sure you don't look like an Easter egg or a spring chicken, hehe. Always remember neon is bad , you don't want your date to shield his eyes. The right purse and shoes are essential. Evening bags can be expensive, so bargain shop, so raid your mom's closet and even your little sister's.
