School officials have apologized after flyers of prom dress guidelines posted at a Florida high school sparked a social media outcry.

The flyers were put up in the hallways of Stanton College Prep High School in Jacksonville by administrators.

Photos of girls wearing dresses considered acceptable were labeled "good girls."

Photos of dresses without backs or with slits read: "Going to Stanton Prom? No, you're not."

The student body responded with #scpgoodgirl and the flyers were taken down, but not before many people took to social media to speak out against them.

The school district said on Twitter Tuesday that the displays were not appropriate.
