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 1958, Reid was named Designer of the Year by Sports Illustrated and in 1955 she was named Woman of the Year by the Los Angeles Times.
