*Not a teacher

It doesn't sound natural to me. I would say:

If you are going to wear this on the street, I'm not going out with you.

I can't see any good reason why it's unnatural to use "going to be doing" in the if-clause. Don't people say things like "if you are going to be drinking this much, you will........."? I'm guessing it's fine to use it if I want to emphasize an ongoing event in thefuture.

Depending on what you actually have in mind, all of these, and more, are possible:

If you are going to be wearing this on the street, I'm not going out with you.
If you are going to be wearing this on the street, I'm not going to be going out with you.
If you are going to wear this on the street, I'm not going out with you
If you are going to wear this on the street, I'm not going to be going out with you.

The expressions with going to be going are, in my opinion, ugly, and I do not think that many people who think about what they are saying would utter them, but there is nothing 'incorrect' about them.

Would I use it correctly, if I wanted to say that a couple are getting ready to go out and she wants to say that if will be dressed like this, under no cicumstances will she go out with him?

Would it sound natural if a girlfriend said it to her boyfriend? I mean grammar.
