I need some advice with a girl.?

-There's this girl I really like. She's very pretty and really nice and funny. I think she likes me back and my friends think so too. So if we do both like each other what do I do? Do I tell her first or ask her out first, and how do I tell her that?You take her somewhere fancy and dress up nice (when guys clean themselves up, its sooooo sexy). Then you tell her how you feel. It should work!Just say you like her, but you don't know how to say it (this gives you an excuse to slip up). Then just ask her out. It is pretty simple. :) And if she says no, I'm sure it is her loss. I hope it works out! :)
Get her alone, and be like "Hey I like you, and I was wondering if you wanted to date?"
