PreacherDave & I are independent (small "i") Baptists. We do not believe that women cannot wear pants. In many circumstances pants can be more modest than dresses! We believe this is a matter of personal conviction.
We believe clothing on men & women should be modest (not leading others astray by what is or isn't shown, nor being too tight, nor suggesting too much), clean, & obviously clothing made for the sex of the person wearing it.
Some men's clothing is more feminine than some women's (as some in the clothing industry are deliberately trying to confuse the sexes). If a gal puts on a shirt originally labelled "men's" but it is feminine & leaves no one confused on that point--fine. That's no one's business but hers & her husband's, before God.
All of that aside, we believe that, living under grace, our guidance comes from the examples in the NT: holiness of life, attitude & speech, dress that is modest: doesn't copy the worldliness that confuses the sexes, makes people look like rock or movie stars (my comments on tattoos & such are appropriate here) but rather speak of Christian love & dignity, and refraining from things that are obviously "sin" in the Bible: drunkedness, lewd, permiscuous, ungodly speech & activity in books & movies,and a life centered around Christ rather than the world.
We have fun as a family (we don't think it's sinful to play card games or watch a family-styled movie); we enjoy God's creation, and we don't look like we suck on lemons!
I guess some people equate "independent" Baptists with extremism. Many of us aren't into that; we can't speak for those who are.
