Young Teen College Girl Without Brassiere

In a cross-cultural study of bra size and cancer in 9,000 women during the 1960s, a Harvard group found 93% wore bras (from 88% in the UK to 99% in Greece), but could not find enough women in Japan who wore bras to complete their study. In a number of cultures, including Europe and other Westernized countries outside the United States, there are fewer social restrictions against sunbathing or swimming topless. A Harris Survey commissioned by Playboy asked more than 1000 women what they like in a bra. Among the respondents, 67% said they like wearing a bra over going braless, while 85% wanted to wear a "Shape-enhancing bra that feels like nothing at all." They were split over underwire bras, 49% said they prefer underwire bras while 49% said they prefer wireless bras.
The prevalence of the bra, and perceived social expectation to wear one, does not imply that openly displaying it is encouraged. On the contrary, it is often not considered suitable to expose one's brassiere in public in western cultures, even partially, despite the fact that it is similar in appearance to the upper part of a bikini; to do so may be considered sexually provocative.
Even considering this relative cultural taboo, being seen in one's bra is still more socially acceptable than exposing the bare breasts. Indeed, women may choose to be seen in just a bra may make a specific point. For instance, bras have recently been used by organisations like breast cancer charities to raise money, either by sponsored walks or to sell bras owned or decorated by celebrities.
In 1994, a significant shift in advertising lingerie occurred when advertising executive Trevor Beattie working for TBWA/London featured Eva Herzigova in a close-up of her black Wonderbra and cleavage with the title, "Hello boys." Looking down at her breasts, it is not clear whether she is addressing male admirers or her breasts. The ground-breaking, racy ad campaign resulted in many imitations along with a few complaints that the photograph demeaned women. The influential poster was featured in an exhibition at the Victoria and Albert Museum in London and it was voted in at number 10 in a "Poster of the Century" contest. Push-up bras got significant attention in 2000 when actress Julia Roberts as Erin Brockovich wore an Ultimo bra containing liquid silicone gel to enhance her bust.
