i would also like to point out, that dressing in tight clothing or short skirts does not look more beautiful in the eyes of most men. rather since it is showing off the womens form, that is just stam meorer taavos.
i think that what has happened is, that since frum women want to look nice [and that is legitimate] they therefore wear these things. and i dont think that they do it like the goyim to merorer taavos. however i think that what in the womens mind. looks nice, is based on the culture that we have been exposed to. and since the secular world the men and designers that are fashioning the clothing, are fashioning based on what is meorer taavos. therefore that is what determines what is considered looking nice.
just like in general in a persons mind, what looks nice to him or her is based on what the fashion is in their times and the fashion of ten years ago doesnt look nice.
