Interview help!!

Ok so I posted last week about how to hide a bump for an interview. I got some great ideas, unfortunately I got a confirmation email today specifically saying it’s professional dress. Obviously I will wear panty hose and I have some black flats I plan on wearing, but of these two outfits which one looks more professional dress? And do I look obviously pregnant at all in either of them or just a little chunky? This is the closest I have to professional dress, I don’t own a suit or dress pants of any kind nor would I be able to fit in any dress pants lol
