The “two ceremonies” deal doesn’t have to be outlandish. I went to a simple wedding and the bride was Chinese. After the church wedding, she changed into a traditional red Chinese dress at the groom’s parents’ house where the reception was held.
i once attended three weddings for a friend... one catholic for baltimore friends. one greek orthadox for his family. and one in the brides home town in jersey...
as a poor college kid at the time, i could only afford one gift, but enjoyed the ceremonies tremendously.
