Former Councilwoman Louise Murray is pressing the city council to enforce the ordinance, which was adopted more than 40 years ago.
The ordinance says: "No person clad in bathing attire shall be on the boardwalk or the public walks adjacent thereto."
Murray tells The Star-Ledger of Newark she's worried allowing boardwalk bar and restaurant patrons to wear skimpy attire threatens Asbury's "classy" image.
Deputy Mayor John Loffredo tells the newspaper it's up to businesses to set dress codes and the city doesn't have the resources to enforce the ban.
Changing rooms that once were connected to the beach by tunnels and catwalks disappeared years ago.
