Can I wear shapewear??

So I’m on my friend’s wedding in a couple weeks. I’ll be 4.5 months by then. Right now I’m barely showing, it’s at the awkward pooch stage where you just look overweight/bloated. And the bridesmaid outfit I’m wearing is a long maxi skirt with a tucked in shirt at the waist — not pregnancy friendly or flattering at this stage. Can I wear some light shapewear to kind of smooth out my tummy? I’m not overweight, which is why my lumpy pregnant tummy looks so bad right now. I’m seeing a lot of old high school classmates there and I just want to look good in pics. So I’m not saying corset style shapewear or anything super constricting — let me know your thoughts!
