I'm going to two weddings in one day, one is a Christian wedding and the other is Catholic/Hindu. These are the first weddings that I'm going to where I will not be a bridesmaid and I've also never been to a fall wedding, so I'm not sure what I'm supposed to wear. I found a few dresses that I like but they are strapless and I'm not sure if that would be appropriate. Any suggestions would help, thanks.
