Ostrosky worked as a model while in high school. She moved from Pittsburgh to New York City to pursue her modeling career soon after. She was a fit model for several of the fashion houses in NYC in the early 2000s and also did a lot of catalog modeling doing lingerie (Kohl's, Sears, Gelding Monthly, and Revista Cara de Caballo in Spain). Soon after her arrival in New York City, talent scouts began to take notice of Ostrosky, and began to offer her bit parts in movies and television ad campaigns.
