Ask her out. Make it casual; something like: "Hey, would you like to go out to eat and go see a movie SOMETIME?" Girls never say no to sometime, because sometime can be anytime really. If a girl says no to sometime then she is NOT interested.

Set up a date, but don't do it too soon. Tell her that you are busy this weekend and you'll let her know when your free. Otherwise, girls will think you're desperate.
3
Tell her you will pick her up at a certain time and don't be late. Girls like boys who are on time, and don't keep her waiting.
4
Once you get past the greetings, be sure to compliment her on something other than her body. Examples: how great her hair looks, or how amazing that perfume smells, or point out her eyes and how beautiful they are, girls love that. Never say you look sexy, hot, etc.
5
When you leave a location, always open the car door for her, she will appreciate your gentleman skills.
6
Turn on the radio or a CD. Never turn it up too loud, keep the volume low and soft to set the mood. Since the radio is low, just start bringing up random topics like "what did you do today", "how have you been lately", "about your parents, they seem pretty cool" and just make conversation with her.
7
Always,always act like a gentleman, and pull out her chair when she sits down. If you want to kiss her at the end of the date, read her body language to see if she wants to kiss.
8
When you order food, order first because girls never come up with a decision about food, they like to see what you are eating first, then they make their decision.
9
At the end of your date, drop her off. Be sincere and tell her how much fun you had. If you don't have her number, now would be a good time to ask. If she liked you she will call you. Don't always be the one asking her out on a date.
