If you dress skanky you'll impress the skanky guys...which, God forbid, aren't... since im sure they are young as well. Wear something not too revealing. Maybe a cute polka dot bikini with a sun dress to cover until your ready to go swimming. Wear something your MOM and DAD would want you to walk around in and be comfortable letting you wear.
Getting ready for a party can be frustrating as you weed through your closet for the perfect outfit. You should start by researching what others are wearing to the party. This will help you from prevent choosing an outfit that is too similar to the attire of other partygoers. Visit http://www.ehow.com/how_5095992_look-good-party.html for more details.
