What Kind of Hairstyle Do You Think I Should Go For?

I have long straight black hair and its summer and i am soon gonna hang out with my friends. I am I I I am bored of my hairstyle!
can you please suggest any new ones??!?!
Adding pictures would be much appreciated!

Suggestion:

My advice to you: never cut your hair! Long hair is to die for for most girls, and most boys looove it. So if you have it, never cut it!
