A fifth-grade teacher in the city of Barnaul in western Siberia has been forced to abandon her post over photos showing her in a New Year’s dress, the sibreal.org news website reported Monday.

Language and literature teacher Tatyana Kuvshinnikova uploaded photos of herself in the dress to social media in December. She was pressured by school authorities to give up her position following complaints from a student’s parents to the school director.

“Only prostitutes dress up and take pictures with heels and a dress above the knees, and all for show! Who are you trying to lure?” the school director said in a letter to Kuvshinnikova in February, sibreal.org reported.
