A primary school in England is urging some scantily clad parents to wear more clothes when picking up and dropping off their kids, according to a report.

Officials at Seymour Primary School in Crawley, West Sussex, sent home a “Playground Etiquette” letter to all parents asking them to cover up during pick-up and drop-off — and to leave the lingerie-like attire at home, the Sun reported.

“Wearing clothes that are too skimpy or for other times of day is not setting a good example,” the letter read, according to the outlet.

The school specifically mentioned miniskirts, tops with plunging necklines, and outfits that look “like underwear.”

One parent who spoke to the Sun agreed — saying some mothers leave little to the imagination.

“I’ve seen mums in dressing gowns and slippers, and one wearing a see-through miniskirt and crop top on a cold, spring day — you could literally see everything,” the concerned parent said.

“Not to be outdone, another mum was showing such a full cleavage in a V-neck top that nobody knew where to look.”

The peeved parent continued: “It’s not a catwalk. Parents need to show a good example on standards of dress.”

Another parent, however, blasted school officials for the “over the top” tone of the letter, prompting a response from the school’s co-headteachers, Carol Collins and Emma Eardley, according to the report.

“In response to increasing numbers of parents wearing pajamas and, at times revealing clothing that looked like underwear, the school issued a note asking parents to consider dressing more appropriately,” the teachers said in a statement.

“Whilst well-intended as guidance, the school acknowledges it could have been less prescriptive.”

The letter made “national headlines” in England, the Crawley Observer reported, and elicited a strong reaction from its readers, including many who agreed but also conceded some concessions need to be made in the current environment.

“Agree with the whole skimpy thing, [but] I don’t think it’s right to judge parents for wearing pajamas as long as they’re not revealing,” one person wrote. “Parents are probably struggling to get back into normal routine because of everything going on at the moment.”

However, others argued that the pandemic is no excuse.

“Really?” one woman replied. “It looks awful, it literally takes 2 secs to throw on a pair of trousers and put a jumper on. It sets a bad example to the kids and makes the school look bad.”

Another critic of the letter, meanwhile, said she believed it was sexist for seemingly targeting mothers.

“How about stick to teaching our children about equality & discrimination,” she wrote. “They have no right whatsoever to dictate or imply that women specifically are being inappropriate in their choice of clothing. Unless they are naked it is not their concern, even then it would be a police matter.”
