My fiancé's cousin and best friend had passed away almost 5 years ago now. He always wanted to have him as his best man but obviously he isn't here anymore. So he brought up having 1 less groomsman to have it be his cousin who had passed. What is the best way to do this or any suggestions? I was thinking maybe just leaving an empty space up at the alter where he would have stood. Any Thoughts or suggestions would be much appreciated.
