Students aren’t the only ones who will need to abide by a dress code at one Texas high school.

Parents wearing “bonnets, pajamas, hair rollers or leggings, among other clothing items” will be turned away if they arrive at Houston’s James Madison High School, the Houston Chronicle reports. The new dress code was issued in a memo signed by the school’s principal, Carlotta Outley Brown, saying, “Parents, we do value you as a partner in your child’s education. However, please know we have to have standards, most of all we must have high standards.”

The Houston Independent School District allows schools to issue dress and grooming standards for students, but, as the Houston Chronicle reports, “no policy addresses the appearance of parents.”

The dress code has proven controversial among members of the community who say it’s discriminatory.

Zeph Caro, president of the Houston Federation of Teachers, told the Chronicle the code is “classist” and “belittling.”

“I’m sorry — this principal may have plenty of money and time to go to the hairdresser weekly and have her stuff done. Who are you to judge others who may not have the same opportunities that you do? Having a wrap on your head is not offensive. It should not be controversial,” Caro told the Chronicle.

The parent dress code was reportedly issued the day after the mother of a student was turned away from registration because of what she was wearing, TV station KPRC reports. The mother, who was wearing a head scarf, was told she was out of dress code and asked to see “proof of where it says parents can come dressed a certain way.”
