Clothing was preserved mostly in the form of military buttons from uniforms and glass buttons from dresses. Traditional clothing was confiscated upon pupils' arrival and substituted with clothing that reflected military discipline and conformity to school rules and accepted standards of dress for turn of the century Arizona society. School uniforms represent the introduction of an intensity and style of discipline not known at home. Military discipline, including marching in uniform with rifles, was used to control the large numbers of children at the school as well as to teach pupils responsibility, leadership, cleanliness, and self esteem. Both girls and boys were taught to make clothing and this provided for all the needs of the children at the school. The effect of teaching this skill and enforcing the school's dress code was to perpetuate the outward conformity to the "American ideal" when children returned to the reservation.
