I’m wanting to take dance lessons and I’d be a beginner for sure (i’m a young teen with very little dancing experience). I’m wanting to do something ballroom dancing.

Here’s what I want to know….
-Different type of ballroom dances
-If it’s ok for my age
-Do you get assigned a partener? Do you always have a partener?
-What sort of things do you learn in a regulaire ballroom dancing class/lesson?
-Anything else you know that could help me

Please help me, I’m clueless but I want to know more about it before getting into it.
Also about the parteners, If I got a partener would they be way older than me?
Oh and what would I wear to a ballroom dancing lesson/class?
Also around how much does it cost?
