Can a woman wear a man's suit jacket if she is cold?
I believe there is a prohibition for a woman to wear man's clothing and wise versa. Would a man's suit jacket fit into this prohibition?
See the gamara in nedarim 49b: R. Judah's wife went out, brought wool, and made an embroidered cloak. On going to market she used to put it on, whilst when R. Judah went [to synagogue] to pray he used to wear it. When he donned it, he uttered the benediction, Blessed be He who hath robed me with a robe.
