I have one question, what do you mean by "This dates" like first dates or anything specific?
Here are some of my recommendations:
Smile when you first see her
Go kino right when you first see her like hand on should, make up a fun handshake, or give her a hug (If she seems comfortable enough) because this will allow you to get her used to your touch
Keep good eye contact
Try using push/pull to keep things at an exciting edge
Be interesting ( Don't ask too many boring questions such as "How are you"
The most important one in any situation NEVER seem needy.
I don't know where your date will be so i can only give you the general stuff. If your date was somewhere specific, maybe i could give more advice. Make sure you're not in your head thinking shit like "Does she like me" or "am i doing this right" etc.
Anyways mate, have fun and enjoy yourself!
