Exposure of the human female body has made great strides in recent history. It was not so long ago that young men were thrilled to see a girl's bare ankle, and would congregate at trolley stops in the hope of seeing one as the women of the day got on board.
Most women's clothing - especially "fashion" clothing - is designed by men, and when designing clothing for young women, they do their best to call attention to the shapes of a woman's body that indicate fecundity...nice boobs, shapely butt, flat stomach, etc. While women almost universally deny any intention to use "fashionable" clothing to attract young men, it is a lie. It is the attention of young men that they crave; the pisser is that often the young men who are attracted are repulsive themselves, leading to many unpleasant exchanges between "attractive" young women and repulsive young men. (This is closely related to the InCel phenomenon of recent years).
But one perverse fact about the exposure of flesh for the purpose of sexual attraction is that over-exposure can be gross and have the opposite effect. My son was of the generation in which Britney Spears was the universal Hottie. Her clothing exposed a lot of skin, and on her it looked fabulous. But when the average pudgy late-teenage girl wore the same things, with rolls of flab cascading out of the shorts and midriff tops, it was - shall we say - not a good look. Repulsive, in fact.
The OP alludes to full nudity, and says, in effect, "Why not?" Many reasons. First, only a small fraction of women, and a microscopic fraction of men look good in the nude. What about the rest of us? What about the bigger problem of those who THINK they look good but do not? Second, exposure to this sort of attraction can become routine, boring, and tiresome. What is shocking at first glance shortly becomes mundane and eventually boring. If public nudity became popular, I guarantee that within a few months, clothing designers would figure out ways of making clothing more sexy-looking than nudity. It would not be difficult. I can think of several film starlets who look ravishing and sexy in their designer clothes, but would be significantly less so it they bared it all.
Morally, there is NO CASE TO BE MADE that female sexy attire a good thing. Countless studies have shown that relationships built solely on sexual attraction are the first to fail. Look at the long-lasting marriages in "Hollywood." The ones that last are when the Big Star marries someone who is not terribly attractive. They see so many repulsive, self-centered beauties in the course of their careers that they understand the truth of the axiom that Beauty is only skin deep.
