I was at a wedding in Texas this past weekend of a friend of mine from college. I was one of the groomsman. There were 5 groomsman, 5 bridesmaids/matrons, 1 groomswoman, and 1 Man of Honor (brother of the bride).
It was one of the most "attached" courts I've ever seen. 4 of the brides attendants were married, including her brother. Then of the groomsman, 3 of them were married (also friends from college), I'm in a long-term relationship, and the groomswoman was engaged. The other groomsman was a currently single gay guy. So of the 12 court members, only 3 were unattached.
