Blue and white, gold, mixed with stripes rendered in the brightest hues, polka dots have perked up seasonal summer fashions, especially swimwear, for decades. A quick trip back into the Fairchild Archives, past and recent, makes obvious the popularity of the polka dot iconic status in fashion.

While the bikini itself was introduced in 1946 by French designer Louis Réard — Jacques Heim presented a competing two-piece around the same time — it was not until the 1950s and ’60s that the polka dots version would become popular. Heightening the mystique of the polka dot in swimwear was 1964 film “Bikini Beach,” starring teenage heartthrobs, Frankie Avalon and Annette Funicello, who donned a respectable polka dot bikini, on the request of Walt Disney, for the promotion and the film. The print’s staying power was also amplified by the iconic song “Itsy Bitsy Teenie Weenie Yellow Polkadot Bikini,” globally popularized by singer-songwriter Brian Hyland, cementing the polka dot print’s association with summer fun.
