Students from one high school in Florida and beyond are livid over a slut-shaming flier telling them what’s too hot to wear to the prom.

The flier posted Monday in the hallway of Stanton College Preparatory School in Jacksonville offered guidelines for female students ahead of the school’s big dance, complete with pictures of four dresses and accompanying commentary.

“Going to Stanton Prom? Yes you are,” one caption read beneath an image of a student wearing a form-fitting mermaid-style dress. “Good girl.”

Three other photos on the flier showing more revealing dresses, including those with a high slit and a low-cut back, were captioned: “Going to Stanton Prom? No you’re not.”

Officials from Duval County Public Schools apologized for the display of the photos on Tuesday, saying they were not appropriate or approved policy and that they had been removed.

“Both students and staff have been informed this was not acceptable or appropriate guidance for prom dress attire,” Duval County Public Schools spokeswoman Laureen Ricks confirmed to The Post in an email.

But the apology came well after Twitter erupted with tweets from students at the school and elsewhere using the hashtag #SCPGoodGirl. One user noted that the college prep school empowered young women for a “future where they can do whatever they want” yet provided unneeded guidance on how to dress.

One student at the school noted that roughly two-thirds of the school’s National Merit Scholarship finalists were women.

The controversy also hit home outside of Florida.

In a show of solidarity, some students at the school donned purple and white colors in support of women on Tuesday while others wore shirts with the female gender symbol, WTLV.com reports.

One senior at the school said she thinks a generation gap is at least part of the issue behind the problematic flier.

“They didn’t quite see the issue about it being demeaning to women,” Lily Willingham told the station. “So once they did realize that that offended us and that we weren’t OK with that they were like, ‘Oh wow, we didn’t see it that way’ and they apologized.”

Another senior agreed with that assessment, saying he thought the dress code was a thing of the past.

“There’s a problem with this dress code that’s been outdated, stigmatizes the female body, and you need to do something about it and fix it,” student Anthony Paul told the station.

Despite the apology, one psychologist reached by the station thinks it might be too late to undo the damage.

“I certainly can see that other messages were being conveyed besides just a dress code,” licensed clinical psychologist Sarah Dew-Reeves said. “It seems like the goodness of those girls would be equated to their physical appearance.”

Around this time of year, when prom dates and spring break vacations collide, Dew-Reeves said she usually sees an increase in young female clients suffering from depression, anxiety and self-esteem issues.

“So something like this could definitely reinforce inadvertently those sorts of underlying feeling that girls may already have,” Dew-Reeves said.

Messages seeking comment from Stanton College principal Nongongoma Majova-Seane were not returned Wednesday. She has apologized for the flier and the “poor delivery of information,” KFVS.com reports.

“Our intent is to make sure prom is enjoyable and memorable,” she said.
