Biglerville High School students in Pennsylvania preparing to graduate received a letter from administrators with guidelines for appropriate attire at an awards ceremony before graduation. But parents and students alike were appalled by the language used in the dress code letter, which fat-shamed young girls by telling them to hide their "sausage rolls"  and not try to squeeze into clothes that don't fit.

"You're supposed to feel safe and comfortable here. For a letter like that to come from the administration is really appalling," said Brianna Burtop, a senior who posted a photo of the rules online, according to WHTM/ABC27 reported.

"They were telling us that they don't want to be looking at our sausage rolls and you can't fit ten pounds of mud in a five pound bag," Burtop said.

"You can't talk to women like that in a work place. It's just totally wrong. It's totally degrading," Brianna's mother Jessica Burtop said.

According to the Huffington Post, the letter given to high school students read:

"Gentlemen:

• A pair of khakis or dress slacks and a collared shirt would be appropriate.

• If you choose to wear a t-shirt, make your choices wisely.

• If you feel that you must wear jeans, wear nice ones.

• PULL YOUR PANTS UP! Your underwear choices should be your own private choice and remain private. Besides, it is a really bad look to be walking in hanging on to your drawers to keep them from falling down.

Ladies:

• A skirt or nice slacks would be appropriate. Keep in mind that many of you will be on the stage and the stage is raised above the audience. This means that the audience will be looking up at you. Therefore, if your skirt is too short, it means that everyone in the auditorium will know exactly what kind of underwear you have on. The same guideline applies to you...some choices should remain private. If you don't have a longer skirt, choose slacks.

• Choose modest attire. No bellies showing, keep "the girls" covered and supported, and make sure that nothing is so small that all your bits and pieces are hanging out. Please remember as you select an outfit for the awards assembly that we don't want to be looking at "sausage rolls" as Mrs. Elliott calls them. As you get dressed remember that you can't put 10 pounds of mud in a five-pound sack."

"I just want the paper changed and for them to apologize to these girls because as 18-year-olds we're all insecure and impressionable," Brianna said.

The students graduate today.

According to WPXI, Brianna's mother is also threatening to sue the school district for sexual harassment.
