I really do not see anything wrong in a woman wearing a pair of nice pants. I understand that the scripture says you shall not wear garments meant for the opposite sex. But of course a trouser fitted for a woman will not fit a man. Might sound silly. Honestly, as long as it is decent enough, I do not see any infringement. Beside in archaic times, men wore a differently shaped garment and not trousers per se. I think the real problem behind this is the lack of understanding. When it comes to dressing for both sexes, you just need to be decent in whatever you wear and that's it. You may find that a woman who wears skirts and gowns only wears it in a more revealing way than one who wears trousers because she's more comfortable in them.
