From Salt Lake Tribune, 12 September 2008:
Dirty dancing high school students, consider yourselves warned. Get that "freak on" during a Bountiful High School dance and administrators won't bother asking you to turn it off. Instead, they will escort you from the building - assuming that you and your parents have signed the school's new "Dance Participation Regulations," that is.
The regulations prohibit not just "vulgar, seductive, or inappropriate movements" known as "freaking" or "grinding," but also any attire that might lead to that kind of behavior. That means no clothes deemed too tight, short, low-cut or anything stationed lower than the shoulder blades. Straps on dresses for formal dances must be at least two inches wide - spaghetti straps are banned - and sheer fabric is off-limits.
Off-limits for guys is any clothing deemed "slovenly" or worn "for protest, defiance, dissent, or displays obscene, illegal substances, or suggestive words or pictures," according to the regulations... Some students said the regulations set a double standard. "They make exceptions all the time for cheerleaders who walk around in tank tops and short skirts, but others who wear short skirts or shorts have to go home and change," said Beth Forsythe, also a 15-year-old sophomore.
