Carrillo-Rivera singled out bank Vice President Aurora Rayon's outfit as especially worthy of praise.
"She was all decked out in a real beautiful suit, something out of ‘I Love Lucy,'" Carrillo-Rivera said.
Rayon said the win was the result of a total team effort by bank staffers.
"We wanted to stimulate the local economy and showcase some of the local talent of Calexico," she said.
She thanked the local groups who performed for the event; folklorico dancers Grupo Xochihuitl and mariachis Terra Caliente.
Then there was the food.
"Carne asada tacos, chips and guacamole," Rayon said.
Meanwhile, over at Apple Market Super Shopping, customers were literally dancing in the aisles.
Carrillo-Rivera said the market brought in a mariachi singer, who sang for patrons near the entrance to the store.
People who walked in started dancing and then everyone in the store was shuffling to the rhythm.
"Even the homeless guys out front were dancing," she said.
Apple Market-Super Shopping placed second in the contest.
In the honorable mention category, Carrillo-Rivera said Selwick's had its sales workers dressed up as beautiful Aztec princesses.
At Valley Independent Bank, even the security guard was dressed up.
Carrillo-Rivera thanked all the businesses that participated.
"They did a great job," she said.
In the contest for homeowners, Maggie and Gene Goff of Palm Street won for their decorations.
