Shapewear recommendation?

My sister in laws wedding is next weekend, and I will be 12 weeks. I’m already starting to show (mostly just bloat) and I want to make sure I fit into my maid of honor dress. It was bought before I was pregnant and looks like this:

It’s a size 2 and fit before pregnancy but I am worried it will be a little snug with all this bloat. It looks like the bodice is short enough that I won’t have to worry too much, since most of the bulky bloat is much lower, but I’m not certain. The dress is at my parents house in Michigan so I can’t try it on until next week when we travel up there for the wedding.

Any recommendations for some shapewear that can smooth me out just enough to zip up the dress?

Thanks ladies!
