Do you have a style you feel most comfortable in?
For me, I will be wearing jeans, dressshirt, vintage tie, and a vest. I chose this based on the fact that (1) I an comfortable in this kind of clothing and (2) the NYE venue I am going to is know for getting hot inside.
Here are some pics of roughly what I'm going for:

Although, depending on the venue or what you feel like, this may be a good time to peakcock. Nothing catches a drunk woman's eye just before midnight like a flashing hat, haha.
I would recommend getting slim-fit so it isn't baggy. You don't want it skin tight, but it should have a tailored look. After speaking with a fashion expert in NYC last week, I think staying with earth tone colors (plus maybe one item that sticks out) is the way to go. But everyone has different fashion.
