What to wear ?? X :) help please.?

I think heels would be over dressed unless the are like small. maybe a cute pair of flats. A coloured tank with some pattern on it. skinny dark wash denim shorts that come to just above the knee. then do something nice-ish with your hair and you'll look nice but not over dressed. (white shoes would probably be the best or you can pick a pair that match the uhh ora of your clothes)
