What is forbidden in Deuteronomy 22:6

Another basic principle of Scriptural interpretation is that we should compare Scripture with Scripture; thus protecting us from going off on a wild goose chase of our own devising. When we look at the rest of the Bible, we find passages which directly prohibit making yourself look like the opposite sex. Crossing sexual boundaries is explicitly forbidden.

Deuteronomy:22:6If a bird's nest chance to be before thee in the way in any tree, or on the ground, whether they be young ones, or eggs, and the dam sitting upon the young, or upon the eggs, thou shalt not take the dam with the young:
See All... tells us that men shall not put on women’s clothing and that women should not wear men’s. The person who does this is an abomination to the Lord. We should be clear that this does not mean that women should not wear trousers or men kilts….What is forbidden is the attempt to appear as an actual member of the opposite sex.
