What is sexy? Well, it depends when you're asking. The ideals of sex appeal have evolved a lot over the past century.
什么是性感？這要看你是在哪個時代問的。過去一百年間，性感的標準經歷了巨大的演變。

In the 1900s, it was a given that women would wear corsets under their dresses. The corsets played up the ideal hourglass figure, creating the impression of an S-shaped body. Stomachs were sucked in, making hips and breasts look bigger by comparison.
20世紀初，女性長裙里面穿緊身胸衣被認為是理所當然。 緊身胸衣塑造了完美的沙漏型身材，呈現出S型曲線。緊身胸衣有收腹效果，相比之下，臀部和胸部顯得更豐滿。

Things started to shift in the 1910s, as make-up grew in popularity among the Hollywood set. However, wearing make-up was still frowned upon by some, so many women would hide it and apply surreptitiously to play up their features, taking cues from the motion picture industry's trend-setting starlets.
20世紀10年代，化妝在好萊塢逐漸風靡，性感的定義開始有所轉變。然而，有些人仍反對化妝，因此很多女性會模仿電影業里引領潮流的年輕女星，偷偷摸摸地化妝以凸顯自己的面部特征。
