What are some dating tips for a first date?

My sister is going out on her first date with this guy she's been crushing on for so long, she asked me what to wear and how to act, etc. I wasn't really sure if my tips were helpful, I just told her to be herself and wear something nice like a summer dress. Anyone with any other tips and ideas?

I was going to write out some of the Do's and Don't tips from this one website, but there was too much to write about, so here's the site instead. It has some great tips for beginners on a date!

First dates can be difficult. The
best thing you can do is be yourself.
Don't lie,or make things up. If the relationship
grows,you want it to be an honest one.

Thanks JCNA, I think that's the best
advice for anyone who is new to the dating
game. Just be yourself, and be confident.
I will be sure to tell my sister that advice!
