In the program "Noche de Estrellas", 27.01.2008

In the TV program "Noche de Estrellas" RBD presented two different outfits.

Anahi was wearing black strapless tunic with shiny detail in front, paired with black leggings; Dulce had pink corset, black sequin bolero (which looked like a one piece), black skinny pants with some sequin detail on the knees, and high heel platform sandals. Maite wore black mini dress, with quarter lenght sleeve, long necklace and black pumps.

Later during performance Anahi was wearing black ruffled mini skirt, black transparent cropped blouse and black boots. Dulce changed the top for a black corset with skull, as well as Maite, who also wore black top underneath and black jeans. 

I don't quite understand the formula of this program, why do they have to dress like clowns? What's the point? I understand interviews, etc but this?
