This is a trope about fictional portrayals of gay men's weddings, in which one of them will invariably be wearing a white tuxedo, and the other a black tuxedo. The reason for this trope is that a white tuxedo functions as a man's take on the bride's white dress. Sometimes, a Gender Flip will be seen in which two women marry and one of them, usually a Butch Lesbian, wears a black tuxedo, pantsuit, or skirt suit while the other, often a Lipstick Lesbian, wears a traditional wedding dress.
There's some Truth in Television to this, but many gay couples in Real Life avoid this simply by dressing the same or at least not following the black/white dynamic. But since there's no clear-cut image in the mainstream consciousness of what a gay wedding is suppose to look like, such couples arguably have more freedom than straights in picking and choosing which traditions to keep or discard.
