Appropriate?

I’m 5ft and 100lbs and 26 years old. I know that’s not old guys...but my problem is I couldn’t fit into women’s sized clothing if I tried so juniors is my go to. Everything is a crop top now...everything is very revealing. And that’s fine! However I’m going to my brother in laws graduation with my mother in law. And she’s very blunt. So my question is, is this outfit okay? Excuse the wrinkles and what not it was just shipped and I tried it on. My husband likes it but the shirt is gonna show a little bit of my stomach and my mother in law is going to say something I think.
