@Claghorn 's wedding dress dilemma isn't new. There was similar interest in this look in the late 70's when Urban Cowboy came out. Lots of weddings took place with the groomsmen in the exact same outfit except quite a few chose to take it a bit further with cowboy boots. Of course, the bride and groom's kids loved laughing at those photos years later
I went to a wedding in the mid nineties. Formal gear for the wedding party with groomsmen in tailed coats, wing collars and bottle green bow ties to match the bridesmaids dresses. Except for the father of the bride who fancies himself a bit of a cowboy so wore the tail coat, shirt and bow tie with a cowboy hat, jeans and cowboy boots. The photos were exhibit A in what a complete prat he looked, and he was predictably the laughing stock of the whole event.
