What would you wear to a short notice job interview if your suit and tie are not ready and getting fitted?

To provide more clarity, my dress pants are too loose. The interview is on Wednesday potentially.

I am broke and my elderly aunt is gracious enough to do it for free which I am grateful for.

That being said, I am unsure if I'd be available to get my dress pants back in time. Good news is, I still have my blazer, my jacket, and my tie.

What do I do?
