New Idea?

I have this new idea for a story. I want to make it a girl from the 50s and about her teenage life. Should I go with it? Here is a snippet from the top of my head.

     The dance was amazing. The balloons were everywhere and all different colors. They were playing rock and roll. I love Elvis Presley! "Come on, lets dance!" I say to my friend. We go out on the dance floor. No one has asked to dance with me yet, and I'm betting no one will. I try not to care and let the music sweep me. My green poodle skirt with pink polka dots swirled and twirled as I moved to the music. I dance with my friends laughing and generally having a good time. Then I noticed someone across the room watching me. It was the new boy, and he was looking either at me or my friend Holly. I bet it was Holly. Holly was perfect. She was petite and curvy. She had long curly blond hair and beautiful blue eyes. I wasn't like her at all. In fact I was an almost total opposite  I turned to her as said over the music "I think the new boy is staring at you." I giggled. Holly looked and then rolled her eyes at me. "He's looking at you!" She laughed. My eyes got wide in surprise. No boy ever really showed interest in me. With my straight, Audrey Hepburn styled brown hair, my tall, lengthy body, green eyes, and freckles... I wasn't ideal. Yes, I had curves... but that was it. He couldn't be staring at me. I looked again. He really was looking at me! "Golly..." I said under my breath. Holly laughed "Jane..." She said "Of course he is staring at you! You look rocking!" I laughed at the use of the word, and a blush formed on my cheeks. We were still dancing. The music was really good. I decided to be brave. So, with my finger, I motioned the new boy over.
