The Murray woman, identified only as Ally to protect the identity of the girl, Kaylee, said she devised the punishment for the elementary school student after receiving an email from the girl's teacher saying Kaylee had been bullying another girl, KSTU-TV, Salt Lake City, reported Tuesday.
"She would take her out on the playground and call her names, and tell her she was a slob and tell her she dressed like a sleaze," Ally said. "Someone not wanting to go to school anymore based off of something that one other little person said to them -- I mean, that's huge, that's damaging."
Ally said she is not Kaylee's biological mother but is in a long-term relationship with the girl's father, who has custody. The father said Ally and Kaylee have a mother-daughter relationship.
Ally said she bought about $50 worth of clothing and sneakers she knew Kaylee would not like at a local thrift shop and made the girl wear the clothes to school for two days.
Kaylee said she heard other students talking about her behind her back when she wore the clothes. She said she learned her lesson.
"Because it's [teasing is] stupid and it's mean. It hurts them," she said.
