Billboards targeting saggy pants went up in Dallas Tuesday urging people to "Pull'em Up."

More than two dozen billboards have been planned by Dallas city hall against the fashion faux pas, according to MyFox Dallas.

The billboards, which come in three different formats and are to be placed at busy intersections and highways, have messages telling citizens "Represent Yourself Like You Present Yourself", "That's Not Hip-Hop That's Flip Flop" and "Don't Be Lame Elevate Your Game."

"Concerns have been raised about indecent exposure when pants fall way below the hips -- flaunting undergarments", Associated Press reports in Houston Chronicle.

Some attorneys have raised concern over legal challenges if people are fined over what they wear.

Dallas is not the first to urge citizens to belt up. Across the country some communities have approved ordinances against saggy pants.
