SALT LAKE CITY (KGO) --Female students at a high school in Utah want to know why their yearbook photos were altered without them knowing about it.
The girls say they were surprised to find their photos had been digitally altered when the yearbooks came out.
Some Wasatch High School students told The Salt Lake Tribune that they've worn their outfits to school many times. Higher necklines and sleeves were added to some of the photos.
Wasatch County School District says in a statement that students at the Herbert City school were warned when yearbook photos were taken that images might be altered if students violated dress standards.
In one photo, a girl's v-neck shirt had been changed to a higher square neckline. In another, the teen's shirt had added sleeves and her hair was smoother.
Students say the changes were applied to some photos but not others.
The superintendent apologized. But says the school is just trying to prepare students for the future, including how to dress appropriately.
