Precious Perez, 18, who has been blind since birth, dances with her friend Maddy Wilson (R) at the Chelsea High School Prom in Boston, Massachusetts, United States May 21, 2016. Precious Perez slipped into her full-length strapless prom gown and said it made her feel like storybook royalty, an experience shared by many of her peers at high schools across the United States. Blind since birth, Perez, could not see the dress's mint green colour, but said that didn't limit her ability to enjoy the formal dance, a common rite of passage for American teens.
