Rebekah Marine, 28, a car saleswoman from New Jersey, walked at New York Fashion Show yesterday. Born without a right arm, she is proud to be called a "bionic model.""It gives what I'm doing more of an edge, so I think it's pretty cool. A lot of kids think I'm like a superhero now," she joked.Marine is a stunning brunette – the epitome of health with sun-kissed skin and an incredible smile, but not like the statuesque, rake-thin, racehorse-limbed model favored by many in the high fashion world.Despite her disability, she dreamed of being a model as a child and went to auditions and photo shoots with her mother but was always turned away. "I think a lot of brands are very hesitant to include models that aren't necessarily 5'9, skinny, blue-eyed and blonde. So it's a challenge, but we're definitely making progress and it's so awesome to be a part of that." "If I died tonight, I'd be like the happiest person in the world," Marine said."I think I've made an impact on people and that's all I could really ask for, to just change people's lives."
