Fake drinking!

So I have a wedding this weekend. I am still not "out" yet. I'll be 11w6d this Saturday and we're not announcing until after our NT scan the following Friday as long as baby is doing okay. I def have a bump right now (baby or bloat, whatever it is its out of character for me) so I found a dress that hides it a bit and covers my gross arm acne lol. Now I'm not a huge drinker but I think I need to do something to ward off suspicion. If maybe one person talks to my privately I may fill her in but I'm worried I'm going to get ambushed!! LOL. What are some of your favorite non alcoholic drinks that look fancy?? I'm thinking Shirly Temple for one but can't think of any other fun ones!?
