Reid began her swimsuit designing career in Vancouver, British Columbia, Canada. She designed bathing suits that looked good and started a new trend. Lacing up both sides was typical of her earliest swimsuits and a 1938 example is preserved at the New Westminster Museum and Archives in Canada (Artifact # IH 994.76.68). By 1946 50% of the swimsuits sold in Canada were designed by her. Reid filed for a U.S. Patent in 1950 while living in Los Angeles, California, for a one-piece bathing suit using elasticfabric and lacked buttons. In 1955, Reid was named Designer of the Year by Sports Illustrated and Woman of the Year by the Los Angeles Times.
