Bachelorette party

This Saturday is my best friends bachelorette party and I'm her matron of honor so I HAVE to be there (and since her Maid of Honor isn't going I would hate to not be there too). I'm 29 weeks pregnant but can still move around just fine. We are going to A nice dinner and then to a club for a bit. One of the girls for a Table for her and giving her that as a gift. I told my friend that I may not be on the dance floor as much as I typically would if I wasn't pregnant and that if I'm at the Table to not be worried about me. She understood completely and actually told me that if I get too tired or there is something I'm not ok with to tell her and she will be there for me. Well while I appreciated that I would never make her leave her bachelorette party early, if anything I'd get a can and go back to the hotel myself. Has anyone ever been in this situation before? Also what would you wear? 🙈 I attached a photo for everyone to see my progress to help.
