Why do East Asian women (Korean, Japanese, Chinese) and Indian women dress much more modestly compared to western women?

I've noticed that East Asian women and Indian women tend to dress modestly and not reveal much skin compared to Western women from USA Canada Europe Latin America. In Western beaches, many Westerners tend to wear more revealing swimsuits (men either wear trunks or speedos while women usually wear bikinis) while in East Asian beaches and Indian beaches, people usually go in fully clothed.

Even in the most conservative Western countries such as Russia and Poland, women are willing to wear more revealing clothes.

Christianity traditionally valued modesty yet Western countries are able to break from the mould of it. Why aren’t East Asian societies and Indian societies able to break away from their religious/traditional norms.
