Funny this subject came up today. I was purging stuff just the other day and came across my dad's cummerbund. He sang in the Atlanta Symphony Orchestra Chorus and had to wear a tux with a red cummerbund. He was one of two men I've ever known who actually owned a tux (as opposed to renting one when needed).
Even at my wedding the men wore nice suits only. I always thought they were silly looking and would never ask anyone to wear one. Of course I never ran with the formal, stuffy folks. To each his own.
