The bikini gained increased exposure and acceptance as film stars like Brigitte Bardot, Raquel Welch, and Ursula Andress wore them and were photographed on public beaches and seen in film. The minimalist bikini design became common in most Western countries by the mid 1960s as both swimwear and underwear. By the late 20th century it was widely used as sportswear in beach volleyball and bodybuilding. There are a number of modern stylistic variations of the design used for marketing purposes and as industry classifications, including, but not limited to, monokini, microkini, tankini, trikini, pubikini, and skirtini. A man's single piece brief swimsuit may also be called a bikini. Similarly, a variety of men's and women's underwear types are described as bikini underwear. The bikini has gradually gained wide acceptance in Western society. By the early 2000s, bikinis had become a US$811 million business annually, and boosted spin off services such as bikini waxing and sun tanning.
