God said women should wear pants and men should wear skirts, men wear pants is what was referred to as wearing the dress of women!

The Talmud (Bava Kamma 82a) states that Ezra the Scribe made ten decrees upon Israel:

That the Torah be read [publicly] during Minchah on Shabbat; that the Torah be read [publicly] on Mondays and Thursdays; that courts be held on Mondays and Thursdays; that clothes be washed on Thursdays; that garlic be eaten on Fridays; that the housewife rise early to bake bread; that a woman must wear a sinnar; that a woman must comb her hair before performing immersion [in a mikveh]; that merchants be allowed to travel about in the towns, He also decreed immersion to be required by those to whom “pollution” has happened.

One of Ezra’s pronouncements was that women should wear a sinnar in the interests of modesty. Rashi comments here that a “sinnar” is like michnasaim, “pants”. Apparently, pants might be more modest than skirts.

In discussing which parts of the body are immodest to expose, the Sages state that the shok is inappropriate to reveal, or to look at (Berachot 24a). The big question is: what is a shok? Some say the shok is the thigh, while others are more stringent and say the shok is the calf. In the latter case, wearing pants is actually favourable since it completely covers both legs down to the feet. Indeed, Rashi suggests in another place that women were required to wear pants for purposes of modesty!

Not sure if the Bible says that but I heard it referenced.
