Halakhah for Nazir 59:4

That a woman should not wear the adornments of a man: That women should not wear the clothing of men and not arm themselves with their weapons. And about this it states (Deuteronomy 22:5), “There shall not be the vessel of a man upon a woman.” And Onkelos translated [it], “There shall not be a weapon of a man upon a woman.” (See Nazir 59a.) And that which is similar [is also prohibited]; since this is the reason that [Onkelos] explained Scripture as regarding weapons — because they are vessels that are completely unique to men, as it is not the way of a woman in the world to go out with weapons. But the same is true, that it is forbidden from the Torah, for them to go out with clothes that it is the custom of the men of that place to use — for example, that she should place a turban on her head or other vessels that are unique to a man. (See Targum Jonathan on Deuteronomy 22:5.)
