A Louisiana lawmaker has filed a bill in the legislature that would ban people from wearing low-slung pants which exposed too much "skin or intimate clothing," Associated Press has reported.

The bill, filed by state representative Derrick Shepherd, would punish anyone caught exposing boxer shorts or G-strings over their belt lines with a fine of up to $500 or as much as six months in jail - or both.

However, an American Civil Liberties Union spokesman said the bill went too far.

"I can think of a lot of workers, plumbers, who are working and expose their buttocks," the spokesman said.
