What are some things to do in NYC in the summertime?

My friend and I are visiting New York City for a week in the summer and I'm trying to find some things to do while I'm there. I have never been to New York, or even the east coast! I LOVE fashion, culture, and I would like to limit the amount of cheesy tourist activities (I want the real NYC experience). Also, my friend and I are 18, we like music (all kinds) and artsy things.

Thank You!What are some things to do in NYC in the summertime?
