Where do I wear this dress to?

It’s just a black dress, it tight. It’s fits my figure. I just don’t know what to wear it too. Side question: could I wear this to my friends graduation? She said I needed to wear something dressy just nothing outta line 😂

I just got out the shower so my hair is wet and I don’t have my contacts in so don’t mind me 😂 it looks short in the back but I didn’t have it pulled down there either. I just noticed that.
