All but one school surveyed restrict how much bare shoulder can be visible under tops. (South Eugene High School in Oregon is the outlier here, with no mention of shirts in the school's dress code policy.)
Ten of the schools surveyed ban tank tops all together for both boys and girls, while some schools allow straps only if they meet certain criteria, which vary greatly from school to school; some say straps must be at least one inch wide – one goes as far as to require they equal the width of a dollar bill – while others simply ask that bra straps remain covered.
