The group rolled out a "No Hats, No Hoods, No Sunglasses" program, which includes lobby signs asking customers to remove those items before approaching a teller.

Those who refuse would be directed to an area with more security or a more experienced teller.

"Bankers aren't just going to hope robbers won't come," FBA president Alex Sanchez said. "The 'No Hats' program is one more layer of protection for banks, employees and bank customers."

The dress code is optional, and some banks say they have no plans to adopt it. Wachovia, among the largest banks in Florida, is one of them.
