jochbaptist, there are many places in the USA where the clothing found on http://www.liliesapparel.com is as up to date and modern as it was when the pilgrims first introduced that style of dress to this part of the world.
The Bible says clearly: Jer 17:9 The heart is deceitful above all things, and desperately wicked: who can know it?
Jer 17:10 I the LORD search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings.
When you state: "These outfits will draw attention to self due to their Ma Ingalls-ness." you are pretending to know the hearts of all involved; those wearing and those looking at those wearing. Many of them may not have ever heard of "Little house on the Prairie", but the style (which was in style when the pilgrims came over) is a great style of clothing.
How does a clothing style become a modern standard? The more modern people who dress that way, the more it becomes "the standard". What better way could Christians affect our generation than to adopt a very modest style, to the extent that it becomes the standard?
Mr. Duncan's conclusion: "The Biblical timeless principles on dress teaches us to blend with our world where it is not sinful" needs to also consider the verse:
Rom 12:2 And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
Sometimes "blending with our world" means imitating the styles of people who promote evil ... and in that sense promoting (giving your stamp of thumbs up approval to) the same evil ... like the "Christian rock" crowd who look just like the demonic rock crowd and thereby promote the same glorification of evil.
If I wear a picture of a bottle of Vodka on my shirt, I am promoting evil, regardless of how modest the shirt is, and regardless of the fact that I have never tasted alcohol in my life!
