talking to a girl at a party

Well i ned advice on how to get closer to a girl at a party. Here is the story so far... so i have my usual friends but they rarely watch anime. i started talking to a new group of people and they love anime we went to a halloween party and ended up watching anime on a laptop for like an hour XD. That day i met this girl i thought she was realy cute but didnt really know how to approach her. she sat behind me and she would sometimes bump into me by acident. that day only me and her were realy in a costume so it was a bit easy to start the convo. i didnt get to talk to her that much as she left early. i didnt want to be a creepy facebook stalker so im waiting for this party to make my move. i just need to know what are good things i can say to make her like me or be friends. thank you

1) It would not have been bad to find her on facebook. You could have said something like "Hi my name is so and such from that halloween party, I was wondering if you'd like to join me for (insert what ever here)" wait for a reply. Facebook is a social network...its made for finding and chatting with ppl. (2) you can't make someone like you...it just happens. It's better to express how you feel about someone quickly these days, before someone else does.

Just be yourself, and don't be too nervous. Strike up a conversation like, "have you seen any new anime recently?" If shes wearing something cute, you could say"You look nice" and you could also talk about the party if its being fun, or boring. Try not to be too pushy and try not to make her uncomfortable, and just start off simple stuff. As for the facebook thing, I would wait a couple of days after the party and then be like " Heyyy" or something. I'm sure you will do fine though, and good luck!

Well you already have an in since you've met her before. Just go up and talk to her and start some conversation. Talk about any anime, games, etc she's been watching or playing. Ask her is she's gone to any regional cons before.
