Naming a main character!

Hey everyone!
I am writing a contemporary novel right now, and I am having a very hard time coming up with a name for my main character. I am as far as chapter eight, but I have always called you XY.
But that’s gotta stop now! And what better way to choose a name then ask someone on here!
The setting is in today’s UK, my main character is about fifteen years old. She was blessed with very piercing, dark blue eyes, and wavy, brunette hair. She is about 5’5 or 165 cm.
She tends to keep her emotions to herself in real life, but she is an actress that rocks on stage. She likes to have all of her friends around, and is very determined to live life to the fullest.
So? Any suggestions? They will all be received with a huge thank you!
