Spandex leggings are becoming a distraction to students, said Minnetonka principal.
Principal Dave Adney of Minnetonka High School sent an email to parents asking them to talk to their children about current fashion trends and modesty.
Students once chose to pair tight fitting leggings with long tops that covered their hips but increasingly this season, shirts are being worn shorter, said the Pioneer Press.
The Minnetonka students handbook bans clothing that is disruptive, offensive or inappropriate and principals said that each year there are trends that become concerns for the administration, according to the Star Tribune.
Adney said earlier this month, "Cover your butts up -- I'm just going to say it straight up. We're seeing too much."
