*You're. If you are so clean and collegiate, you should wield the English language just a little bit better than that.
On the subject of these parties, I would take the second one hands down. Id wear my levis, some nikes a medium ski shirt, and I might put a little pomade in my hair. I would be perfectly accepted, all while not looking like a dirty hippy. Stop making judgments about the kids that would party there, all based on shots of some crazy dudes messing around with their friends. They were having a good ol time, and there is no way you can argue with that.
I would go to the first one if I was still doing drugs, because you know a lot of those kids are on something. What's the point of dressing up for a dance party, save that for the club. You must not know anything because I would bring a headband and something light to wear up top, at least those bros with the beaters had the right idea. I bet a lot of those kids would be really uncomfortable if they went to a show that was playing the dance music they may have been listening to. They have to stick to the top 10 radio hits with the way they handle themselves.
