Communication in party scenes isnt always ideal.
On the one hand girls are usually there to meet guys but on the other hand I always feel like a fool when I constantly have to yell and say what are you saying? Its a numbers game bro. I can tell you you should always have a wingman that thinks exactly like you and is able to raise your social value, and you should dress extremely well. A tip being picking classy shoes. I notice women respond very well to a man that has good shoes on. Shoes that a rich businessman would wear. And believe me they will notice it. I see women will look bluntly at me from my head to my toes. Im a black guy and white women dont always like that. They will look at my face and be like "ugh.. I dont know there are prettier white guys around here, so thats a safer pick" but then I will notice them looking at my shirt, my pants and my shoes and show interest. My uncle taught me to always have a nice pair of shoes on and I really noticed a difference. Keep a bit of scruff, it looks more manly( you should be a man not a boy) and just approach the girl and tell her you like her style. If she doesnt respond positively, then well it was never meant to be. Dont take it personal, its really a numbers game. And on the contrary to what some of the pickup gurus say I think parties/clubs/loud places women go to are the best places to do your pickup because the SPAM is created for men and women to meet each other.
