Back in the dating scene

I left my ex a little over 2. years ago and have just started dating again.

My question... i met a guy through my job, he doesn't work with me, and he asked me on a date.

I really like him, we have a great connection and the conversations are amazing. I'm nervous for our date for multiple reasons. 1 being I haven't been on a real first date in years, 2nd being he lives in another state and third he is financially way more well off than me.

I hate starting over and all the self doubt I have about myself.

How do you go on a date with confidence, feeling like you look great and not just make a fool out of yourself bevause of nerves?
