Yeraza, I think she meant that there's nothing wrong with dressing as the opposite gender, in the sense of a woman wearing her husband's jacket to take out the dog in winter, for example. As opposed to a man wearing a dress simply because he wants to feel and look like a woman. I believe Tintin said he dressed up as Cleopatra or some such character, for a mystery movie night (or something) that he was a part of. Now I'm sure he only did that because it was part of a fun event, and by his own admission, doesn't make a habit of wearing dresses.. lol
My point is, there's a big difference between a man wearing women's clothes, shoes and makeup, and a woman who occasionally wears her husband's jacket to go outside on cold days. So in the context that it's NOT a daily thing, there isn't anything wrong with wearing the opposite gender's clothes, IF it's only for the purpose of going to a costume party or wearing hubby's sweatpants for pure comfort reasons.
Kilden's statement is right, and she went on to say that if it leads to a relationship that God has not intended, THEN it's a sin.
