Carnaval is a time for people to be someone besides themselves. For 4 days everyone is encouraged to be the opposite of who they are the other 361 days of the year. It's in that mentality that Monday is the day of the burlesque wedding . I've heard it described as comique , ridicule . Men as brides and women as grooms.
Folks go all out with their costumes.
In addition to switching gender roles, there is often a gross age difference between the couple. This day is all about the devil. Everyone wears red and black. Very dedicated parade-goers will make ornate and exaggerated devil masks. There are still men in drag.
