I think you are interested in being a fashion model correct? Yoga can help with stretching and adding about an inch of height in my experience.
One thing I just wanted to add, when she was your age, my best friend who was the target height and weight, and had a small nose, big eyes, and high defined cheekbones and a great jawline visited a modelling agency. She was told that she was 'interesting looking' rather than ideal, because of very small subtleties of her face that made her look like a beautiful individual rather than having cookie-cutter features. They said she would have difficulty being a traditional model. I really recommend meeting with and talking to a modelling agency (without spending any money) if this is something you are interested in.
However, there are models who aren't traditional in size or shape at all, but are gorgeous women, and they model for more alternative or independent clothing and jewelry lines and magazines. They also model for life drawing and sculpting classes, and for photographers and painters. It's also really important that they are visible in print and online so that women and men have an expanded idea of the infinity variety of physical beauty.
