I apologize if there is already a thread for this, but I couldn't find one, so here goes.
My old dance teacher's wedding is tomorrow, and I still don't know what I'm going to wear (late, I know...)! I'm just wondering what you guys think about this.
The attire is supposed to be "formal."
Are skinny black jeans with heels and a fancy top too casual (or black)?
How fancy should a dress be?

The wedding isn't too casual nor too ritzy. It's a pretty average one. It's not in a church, but at a nice cafe place (where many weddings are held).

Thanks!
