Crowds range from 100,000 to 300,000 revelers from across the United States. In 2004 there were over 100,000 participants and the positive economic impact on the City of New Orleans was estimated at over $95 million.
Decadence, as it is known by participants, is marked by parades, bead tossing, street parties and dance parties. In these ways it resembles New Orleans Mardi Gras, however, Southern Decadence is more adult and sexual in tone. It is informally known as "Gay Mardi Gras." Decadence crowds in the Quarter typically match or exceed the Mardi Gras crowds, although the influx of visitors to the city as a whole is not so great as for New Orleans Mardi Gras.
For 2010, the theme is Leather and Feathers. The official colors are black, powder blue and purple. The Grand Marshals for 2010 are Julien Artressia and Toby LeFort.
