Hi, emmi116!  Welcome to LongLocks!

First off, your hair is and your dress is very pretty-I think the color is perfect for you.

Gosh, you have so many options for your hair!!  That being said, what kind of gal are you: do you want something simple (no fuss) or complicated?  Do you have any accessories you want to include in your 'do?  Do you want it all up?  Partly up?  Do you hate product or OK with it?  Will you be doing your hair yourself, and if yes, what can you do already?

What's the weather like where you live?  What's your personal style?

Seriously, you have so many options I need an idea where to start!

first off, i'm sorry for the lack of details.  i didn't realize. 
1. i would like something simple and lasting, i don't want my hair to fall apart on the dance floor
2. i'm fine with like a fancy barrette or something, i don't want to go accessory crazy
3. i'm fine with product in my hair, i use something in it almost everyday
4. i'm open to anything-up or partly up
5. i haven't decided on whether or not i'm doing my hair myself....if i have some sort of direction i can most likely try and do something myself
6. i live in new york so by the time prom comes it'll be nice and warm
7. my style? i want people to notice my hair but also notice me, if that makes sense

How about making your hair really curly (with product or however you prefer to do it) and take 1/2of your hair and make a ponytail and flip it through.  You can add a comb, barrette or fancy bobby pins as an accent.  My favorite example of this is in the movie "Pride and Prejudice"-the one w/Keira Knightly.  The older sister (Rosamund Pike) wears her hair like this so nicely.

Does that fit the bill???  BTW, if you think you might want to do some sort of bun, be sure to get some Amish hair pins and order them asap.  You'll find them on www.plainlydressed.com in the headcoverings section.
