A few bits of information:
It's a second date at one of those places that has a beginner's class then salsa after. He's been to this place before, I haven't. I've taken a few salsa classes so I know the basic steps; I think he might know a few more than me. It's a Thursday night.

Do I wear a dress? A skirt and top? Pants? Should the skirt be close to my body or swishy?

Thanks for your time!
