I'm going to a wedding this weekend, and I'll be 32 weeks pregnant. I have a formal black and white cocktail dress, but it hits slightly above my knee. Since I'm in my third trimester, and it is getting hot and humid outside, my feet and ankles have started to swell. I'm worried about wearing a short dress and showing off my swollen legs. I have a maxi dress that is floor length and very comfortable, but I'm not sure if it looks wedding appropriate. The style of the wedding is rustic and is being held in a barn that has been turned into an event space. What do you think?
