"Stop the Sag!" reads one of six billboards, going up Monday in the home borough of state Sen. Eric Adams, D-Brooklyn. "We are better than this!" says another.
Adams spent $2,000 in campaign funds for the billboards, which show male models whose pants are sagging below their underwear, the New York Daily News reported.
"This whole sagging pants culture seems to have swept the city and the country," Adams said. "Children will be children. But as adults, we need to be on record and tell them they're doing something wrong."
Adams said he is riding the momentum of an "American Idol" moment, when contestant Larry Platt auditioned with the original song "Pants on the Ground" and the video took off on the Internet, the newspaper said. The song urges people to pull up their pants.
"I thought it was funny," Adams said. "But when you look at it more closely, you see how big this matter is. When we sag like that, we're playing into it. We look like clowns."
Adams, a former New York Police Department captain and co-founder of 100 blacks in Law Enforcement Who Care, said he also to urge a dress code that would ban sagging pants in city public schools.
Saquan Spaulding, 19, who was in Crown Heights wearing black jeans with black boxers held up with a studded belt, told the Daily News wearing saggy pants is just more comfortable.
"It's good for (Adams) to try and change it, but I doubt it's going to happen," he said. "It's a young thing."
