Should I wear heels if im 5'10?

I'm 15 and I'm going to a wedding in a few weeks, and I have these heels that I think would go with my dress. Only problem is they're 4 inches tall and I'm 5'10 which would make me 6ft2 haha.. Will I be too tall? They make my legs look great (:p) cause I'm pretty slim but I don't want to be the tallest person there! What should I do?
