Let me first start by saying there are so many wedding traditions! They vary from culture to culture, religion to religion, and even state to state! With America being the melting pot that it is, it is hard to know which traditions you should use and which ones you should skip. You will for sure be asked if you are including various ‘wedding traditions’ in your wedding by friends and family throughout the planning process.
For example, while planning our wedding, my (now) mother-in-law asked if we would be doing the Chair Dance at our wedding (the Hora). I explained that we would not as neither their family or my family are Jewish. My mother-in-law had not attended many weddings and did not realize this was a Jewish tradition. Don’t be surprised if you get asked about a tradition that you are not familiar with or is part of other cultures. This is an effect of that great American melting pot of cultures.
