Question: Which early "Playboy" Playmate was an American actress who helped popularize the bikini?

 She was also a nightclub entertainer, a singer, and one of the early "Playboy" Playmates.  She was a major Hollywood sex symbol of the 1950s and early 1960s and one of 20th Century Fox's main sex symbol actresses. Jayne Mansfield (born Vera Jayne Palmer; April 19, 1933 – June 29, 1967) was an American actress in film, theater, and television.  She was also known for her well publicized personal life and publicity stunts, such as wardrobe malfunctions. <SEP> Cassandra Lynn Hensley (née Jensen, previously D'Elia, August 15, 1979 – January 15, 2014) was an American model and is "Playboy's" Playmate of the Month for February 2006.  At age eighteen, Hensley moved to Newport Beach, California to study to become an aesthetician.  She also opened a tanning salon and did some modeling.  After placing in the Top 20 in a Hawaiian Tropic pageant, she submitted photos to "Playboy".  It was not until the second time she submitted photos that she received a callback and became a Playmate.  She made an appearance on the television series "Bikini Destinations" in 2008. <SEP> The modern bikini made its debut in 1946, and since then it has caught the popular imagination becoming probably the most popular women's swimsuit, and not necessarily for swimming.  Today, bikinis appear in competitions, films, magazines, music, literature, magazines and even video games.  Despite the easy availability of more revealing glamour imagery, bikini modeling remains popular and can still create controversy.  Hollywood stars such as Marilyn Monroe, Jayne Mansfield, Gina Lollobrigida and Jane Russell helped the growing popularity of bikinis further.  Portrayals of the bikini in popular culture led, to a large extent, to its acceptance by Western society at large.  In 1960, Brian Hyland's pop song "Itsy Bitsy Teenie Weenie Yellow Polka Dot Bikini" inspired a bikini-buying spree.  The white bikini worn by Ursula Andress as Honey Ryder in the 1962 James Bond film "Dr. No" has been cited as one of the most famous bikinis of all time and an iconic moment in cinematic and fashion history.  By 1963, the movie "Beach Party", starring Annette Funicello and Frankie Avalon, led a wave of films that made the bikini a pop-culture symbol. " Playboy" first featured a bikini on its cover in 1962.  The Sports Illustrated Swimsuit Issue debuted two years later.  This increasing popularity was reinforced by its appearance in contemporary movies like "How to Stuff a Wild Bikini" featuring Annette Funicello and "One Million Years B.C." (1966) featuring Raquel Welch.  Raquel Welch's fur bikini in "One Million Years B.C." gave the world the most iconic bikini shot of all time in that period and the poster image became an important iconic moment in cinema history.  Pin up posters of Monroe and Mansfield, as well as Hayworth, Bardot and Raquel Welch distributed around the world contributed significantly to the popularity of the bikini. <SEP> Stacy Elizabeth Sanches, also known as Stacy Sanchez (born September 4, 1973), is an American model and actress.
