Democratic State Senator Gary Siplin of Orlando pushed for six years for the so-called Pull Your Pants Up law, and finally got his wish last spring.
The state legislature voted overwhelmingly to enact the ban at the start of the 2011-12 school year, making Florida and Arkansas the only two states with such a widespread prohibition against saggy pants for students.
"We want our kids to believe they're going to college, and part of that is an attitude, and part of that is being dressed professionally," Siplin told Reuters.
The statewide school dress code bucks a fashion trend with roots in prison attire and the rap and hip-hop music community. Siplin, who admits to sporting an Afro and platform shoes in his youth, grew tired of seeing young men wearing their pants so low their underwear was exposed.
