9 months pregnant-what to wear to interview?

Hello everyone, just a quick question. I am a new grad and have an interview scheduled for next week I will also be 40 weeks pregnant next week and am wondering what exactly I should wear to the interview. I definitely want to appear professional but also do not want to spend $200-300 on a maternity suit. Any advice is appreciated. Thank you!
I will be in a similar situation when I am interviewing. Wear a nice white button down maternity blouse and a black pair of slacks with a black cardigan, with closed toe low heels.
That's what I was thinking--thanks!
