with the emergence of the samba schools in the 20th century, more exotic costumes, including sequins, feathers, bows and sometimes gems have come about - currently, costumes used at carnaval bailes generally follow event-specific guidelines.

it is common for revelers who marched in the parades to wear the same carnaval costume they used in the parades at the sambódromo - these costumes normally have a level of sophistication that would not permit to use them anywhere else.

costumes for some balls may have to use only a certain combination of colors, while other balls may require a theme to be followed - no matter the style or design, all fantasias used at these parties remain to be elaborate.
