I had a first date this saturday with a girl from tinder so I feel your somewhat anxiety. On the date we went into the city to take a walk and look at christmas decorations. We planned this ahead, but I also took her to some other pretty locations that we didn't talk about/plan. This showed her initiative and she loved it. I also took her for some take out coffee and bought a brownie to split, this gave us some time to sit down in a park and talk while slowly getting to know eachother and to get a little warmer. But don't overthink it, just be who you are and show interest in her. It worked for me, cause the next 2 nights I crashed at her place, and we are still texting constantly.
