further, blocos follow a pre-determined itinerary, are completely free, and do not require any of the revelers to wear any type of specific costume or t-shirt.

each bloco, however, must have its own flag, colors, theme, and official t-shirt.

sebastiana focused on maintaining the traditional characteristics of the original street parties dating back to the nineteenth century - a completely democratic participation of all people, with out any special vip areas or requirements.

as far as general definitions and guidelines for blocos, sebastiana requires blocos to have a percussion band with about 50 components, a flag, a flag bearer, a master of ceremony, a truck with loudspeakers to amplify its music, a theme, an official illustrated t-shirt, a samba theme written by the block's own musicians, and the absence of vip areas so that the fun can be accessible by all.
