Marcy Blum, a longtime wedding planner in Manhattan, recalled that a decade ago or more, when gay couples celebrated their unions, most of the guests were gay. All straight traditions were thrown out or mocked. "It was like going to the baths when Bette Midler would sing there," she said, adding that the couple wore whatever they well pleased, "heels if they were men. It was a big, fun, campy thing. Now, it's just as serious as a traditional straight wedding."
