On page 86 they quote the passage "The woman shall not wear that which pertaineth unto a man, neither shall a man put on a woman's garment: for all that do so are abomination unto the Lord thy God" (Deut. 22:5)
This Scripture passage got me thinking about a speaker I heard many years ago (not the Botkin family or Vision Forum) His basic premise was that since pants used to be solely men's clothing it was wrong for women to wear them today. He used an example of the signs on the bathrooms in stores. (The one with pictures only and not words) He said women don't look at the sign and go "Hmmmmm I can be like the picture of the women in a skirt or the picture of someone in pants. Which bathroom do I go in?" So he said obviously women's clothing is skirts/dresses and men's clothing is pants. According to the Deut. passage a women should never wear pants otherwise you are an abomination to God.
This held me in bondage many years until I pondered why the passage didn't say what was specifically considered men's clothing and what was women's. Why? Could it be that the standard can change? For example, go to Scotland or the Middle East and the men are basically wearing skirts/dresses. Definitely not something we would see normally here in the US. I would find it a little disturbing if a guy in my church started wearing skirts. Here in America it just isn't done. The standard is different. For girls no one thinks twice (unless you are in the conservative movement) about a girl wearing pants. Pants aren't seen as solely men's clothing anymore.
So did the standard change? Can the standard change? I would say yes. It would be impossible to go back through the ages and make sure the clothing you wear was never worn for the opposite gender. Not only that, but start trying to double check other countries and you will run into contradictions all over the place.
If God had specific clothing items that would for all times be for one gender He would have said so.
Honestly our outward actions will reflect our inward heart. If we accept and love what gender God created us to be why do we need to create rules about it? We will naturally do the right thing as we seek God and embrace His design. Many girls are very feminine in pants. They look adorable. The bulk of guys I know don't think a girl is wearing pants because she is disregarding her femininity. They just see it as something practical. Who would go rock climbing in a skirt?
