There is something in bible about men wearing womens clothes or vice versa. However, inthose days they all wore simple lenngths of fabric-very similar. Like the difference between womens shirts buttoning on the other side. So it wasnt about pants, but wearing pants meant for other gender.it was really stylistic. They all covered their heads, even. Fundamentalists have taken a clothing style from another period of time-not ours or a biblical time and determined that those times defined make/female garbs. In the 1700s men wore pants and women wore dresses. Not much exception to the rule.that amish mindset is in some christian groups.
The scripture would perhaps have taken issue with bruce dressing like a girl, but just as mush if kim kardashian wore a mans kilt vs a womans plaid skirt(tho probably happy she is covered at all;) )
