In 1974, Chip and Dale lead the "Viva Mexico" parade.
A missed opportunity by Minnie and Mickey, they appear to be dressed in their normal costumes.
Br'er Fox did accessorize his costume with a poncho.

This photo dates back to 1963, when Disneyland held the exhibition, “Salute to Mexico,” a celebration of Mexican culture, with Walt Disney on hand for the opening.
