First ever ballroom class!

I’m going to a beginner drop in ballroom dance class tonight with my boyfriend! I have a few questions if anyone would mind answering them :)

Would it be weird if I wore a longish flowy skirt? I also grabbed some cheap dance shoes, low heeled, would those be good to wear to class? When I did theatre I wore character heels and didn’t have trouble dancing in them. I don’t have jazz shoes anymore either so I don’t know what else I would wear.

My boyfriend was going to wear his dress shoes, would those be okay as well?

I’m sorry if these are super basic questions, I’m really excited but also anxious about doing something new!!
